Welcome to my blog! I thought that I would try my hand at writing about various aspects of mandolin making on a more or less monthly basis. I say 'more or less' because new submissions will largely be based on wether or not, I have the time and inspiration. New entries will be posted here with the latest one at the top so you can quickly see if there has been any activity since your last visit.

In my sincere effort to make each mandolin better than the last, I am constantly thinking about ways in which I can improve my mandolins. Sometimes I think about a better process, sometimes it's better materials as in the case of the varnish and sometimes it's about improvements in design in order to refine my sound even further.

During my sabbatical from mandolin making, I had a lot of time to just think about what I might do differently to improve my sound if I had the chance. When I was fortunate enough to have that chance, the result was what The late Pete Kuykendall termed "Apitius 2.0". A new generation of Apitius mandolins, markedly different then the ones that had preceded them. Outwardly, they have a look much more closely resembling the Loar period mandolins and inwardly, they have more than a few innovations which I developed to refine what is possible in the sound of an arch top mandolin. My aim is to take the F-style mandolin, metaphorically, from a good Heintzman upright to sounding like a Bösendorfer grand piano!

Two such innovations are shown in the photo below. The first being my unique neck block design which I have been using for quite some time now. In the photo, I have penciled in the the shape of the conventional block. (the curved line to the left) My block is designed to give the top (and back) plate a more solid support just as a speaker with a rigid frame will produce a more powerful sound with less distortion when driven hard. In order to minimize the added weight of my "extended" block, the extra support area is hollowed out in a way that retains much of its stiffness.

A fairly recent innovation are the perpendicular holes drilled in the block near its rear edge. This reduces the block's weight by about 7 - 10 grams. Not earth shattering but like I have learned from the world of custom motorcycles, every little detail adds up.

While I remain committed to the traditional methods of hand crafting each one of my mandolins using time tested materials, I also strive to find innovative ways to continually and methodically improve and build upon "the Apitius sound".


'just for fun, below is a photo of how these neck blocks start out. That's a slab of genuine Central American Mahogany that I will process into neck blocks!

Until next time,

This month's blog is a brief description of the way I create a "rub joint" for the center seam of a top or back plate. For those who don't already know, the top and backs of most stringed instruments are made up of two halves with a center seam in the middle. A flitch of wood is split or sawn in two lengthwise then folded out like the leaves of a book. The two halves are then joined together in this orientation so that one half will be the mirror image of the t'other. This is what is referred to as book matching. It can create quite stunning patterns in figured wood but traditionally, its main purpose is to keep the density/stiffness of the plate as uniform as possible for more even modes of vibration.

Since the top and back will be carved quite thin, especially near the perimeter or, re-curve area, this glue joint must be absolutely perfect. Many larger production shops use a stationary jointer/planer to create the straight edge of the center seam and then glue the pieces together with a clamping fixture of some kind. I myself have used this method for many years with good results but for the ultimate center seam, I have now gone to the tried, true and never surpassed quality of a traditional "rub joint" as used by the greatest violin makers for centuries.

This type of joint requires no clamps but instead utilizes perfectly smooth, plane shaved joint surfaces and the properties of traditional hot hide glue to draw them together. For this joint, I use an ultra strong grade of hide glue with a gram strength rating of 315.

A conventional jointer machine with its rotating knives will inevitably create tiny scallops on the mating surface of the plates. These can be overcome by glue and clamping force but the sheared, dead smooth surface left by a traditional hand plane with a well honed, razor sharp edge is a pillar of creating the ultimate, virtually invisible joint.

My weapon of choice is a Stanley Bed Rock No. 607 jointer plane that I purchased from a trim carpenter years ago. It was made sometime between 1895 and 1902 according to a book of Stanley planes that I once had access to. Back then, these were the state-of-the-art in plane design and quality. Tradesman made their livings with these tools. By the 1950s and 60s, power tools were taking over and hand planes were increasingly a hobbyist's tool. This resulted in less competition amongst plane manufactures and a gradual drop in quality. Today, there are a number of specialty tool makers once again making very excellent quality hand tools but I have come to love my 100 year old Stanley Bed Rock and its sole could not be any truer.

Stanley Bed Rock #607 Jointer Plane Pat'd April 2, 1895


To make things easier and more consistent, I made a simple "shooting board" to help guide the top and back plates over the sole of the plane and keep the joint a perfect 90° to the bottom face of the plate.

The jointer plane and fence are held in place by a vice.


Here is how the shooting fixture works in action............

The fence keeps the inside surface of the plate 90° to the center joint.


When the two halves are perfectly straight and smooth, high strength, hot hide glue is brushed onto both edges.


Here's where the term "rub joint" comes in. With hot hide glue applied to both edges of the joint, the two halves are brought together and firmly rubbed until the joint is well seated. No clamps are needed. The hide glue will shrink as it cools and dries drawing the joint tightly together.

The glue will be left to dry in this position for a half hour or more. It can then be carefully moved to an out of the way location where it will be left to dry overnite before doing any further work on it.

And there you have it. A joint that is stronger than the wood itself with no clamping. Of course this method does not lend itself to high volume production but is another example of a centuries old technique that has yet to be improved upon in terms of absolute quality.

It's hard to believe that it has come and gone already. This is the second year in a row that we traveled down to Raleigh NC for the IBMA "World of Bluegrass" trade show. I have to say that I never could have done it without the tireless efforts of my wife Jody. She spent two entire weeks wading through the mounds of paperwork that it takes to bring a car load of samples and other trade show accouterments into and out of the U.S. these days! For that, I am truly grateful.

The trip down was very pleasant as we wound our way through the Blueridge Mountains, passing Mount Airy, the real life location of the fictional town of Mayberry for those of you old enough to recall the Andy Griffith Show. I believe I saw more than one plastic Andy Griffith perched on the dashboards of the passing cars.

The first morning that we awoke in the friendly town of Raleigh, we had the great honor and pleasure of having breakfast with the extraordinarily talented, Dan Tyminksi! Dan told us about his exiting new career direction, a project called "Southern Gothic". "Whatever you think it is" he said,"it's not that."

I had arranged to show him the new Apitius "Classic Model" mandolin with X-bracing that I had made for him. This will give him a new sound pallet to add to the Apitius that he already owns. I was so happy to see Dan's reaction as he ran it through its paces in the courtyard behind "Big Ed's" restaurant.

Dan Tyminski trying out his new Apitius Classic Model mandolin.
Here I am, doing my best to answer all of Dan's questions.

Dan was so kind and generous to let me use his new mandolin as a demonstrator model at the trade show after only getting to play it for an hour or so. It did get an awful lot of playing over the course of the four day event. So much so that I will have to give it a light polishing before shipping it back to Dan to keep.

I also wanted to show Dan my new "Yorkville" jazz model just to get his reaction and it couldn't have been better. To my utter surprise and delight, he asked me to put him on the list and ordered one right there on the spot! The IBMA show could not have gotten off to a better start!!!

Floating away from Big Ed's Country Kitchen, Jody and I headed over to the convention center to set-up our booth. Last year's motif was a pickin' parlor. This year we went for a more modest pickin' porch and Jody did a great job of organizing and decorating our 10 square feet of prime IBMA real estate.

We truly enjoyed meeting new players and reconnecting with those that we met last year. Bluegrass people are truly some of the friendliest and kind people you could ever hope to meet.

On day two, we were so happy and honored to have the band, Mile Twelve drop by to perform some songs in our booth. They were the winners of the "Momentum" Award this year and for good reason. This band is going places both figuratively and literally. By the time you read this, they will be flying off to do a two month tour of "the land down under". Starting off in New Zealand and then going over to Australia. (I asked David Benedict to tell me if the toilets really do swirl the other way around down there.)

On day three, I met up with Forrest O'Connor of the O'Connor Band and was rewarded with a back stage pass that allowed me to catch the O'Connors perform at the large, open air amphitheater in Raleigh, called the "Red Hat Theater" with "ring-side seats!!!! Forrest and his talented wife, Kate, were so kind and gracious to both Jody and I. Forrest really seemed to dig my mandolins as well. I wouldn't be surprised if the names O'Connor and Apitius are spoken in the same sentence in the not to distant future. I've got my fingers crossed on that possibility.

I also had a chance to spend some brief moments with the legendary Mark O'Connor as well. He couldn't have been kinder. From what I could see, Mark seems to take great delight in teaching and mentoring young aspiring fiddlers and they seem to take to him and his teaching style as well.

Here's Mark accompanying some young talents on a borrowed Apitius jazz model mandolin.

I don't want to end before saying a word or two about the town and people of Raleigh, North Carolina. I have been to places near and far and I have never met more friendly and kindly people than the good folks of Raleigh. If your looking for good places to eat, there are a multitude of independently owned establishments that serve up a wide variety of both local and foreign cousine. From trendy locally grown organics to pulled pork barbecue with local brews, Raleigh has something for everyone. I'm especially found of Cajun fare so Jody and I found a great place in town called "The Big Easy" where I had me some good gumbo and ate 'gator for the first time. I know, I know, it sounds cliché but it actually did taste a lot like chicken.

We met so many good folks at our convention center booth it is just not possible to mention them all. Our good friend, James Cook of Bourgeois Guitars took up the booth next to us again this year and this year, I also got to meet Dana Bourgeois for the first but hopefully not the last time.

Two people came by to play "cripple creek" and say "I don't want a pickle" for their choice of a free T-shirt or blueprint set. A couple of people wore their Apitius Tees from last year which made us feel great. One of them, Greg Silverman even managed to coax me into playing a little "Soldiers Joy" on his Gilchrist A-model (I very rarely play in public).

Greg Silverman and myself playing Soldier's Joy (I'm playing Greg's Gilchrist mandolin)

Well, I could go on for days but I need to get back in the shop. I'll leave you with a collage of photos of some of the people that stopped by our booth. Please accept my apologies if I didn't get you up there (or got your name wrong). We thoroughly enjoyed meeting you all (y'all ?) and very much hope to do it all again next year!

2017 has been an extraordinarily busy year for my wife Jody and I. I took on a number of special projects and then wouldn't you know it, our house suddenly needed urgent repairs. Most years, we have been able to take a couple of weeks vacation, one or both of which were used to take an extended motorcycle tour to somewhere in Canada or the U.S. We would just point the bikes in a chosen direction and see where the road lead us. The longest such trip was 6,000 kms (4,000 miles) in two weeks.

We were feeling a little down by the situation when we came up with an idea to get in at least a weekend getaway. I noticed that one of my endorsers, David Benedict was going to do a house concert in Rhinebeck, NY as part of the band, "Mile Twelve". Rhinebeck! House concert! Two of my favorite things. I have always loved acoustic music played in intimate settings with little or, preferably, no amplification to get in between me and the music. It's the ultimate way to hear music as far as I'm concerned.

Now, the ultimate way to fly is in an open cockpit bi-plane and I knew that Rhinebeck NY was home to Cole Palen's "Old Rhinebeck Aerodrome" where they have the world's largest collection of WW1 flying machines in flying condition! Every weekend in the summer, they put on an air-show that takes you back to the 1920s. The days of the barnstorming air shows, joy rides and fine arched top mandolins.

Combining these two things gave Jody and I a much needed change. We would have taken the motorcycles but the weather was uncooperative on the day we left so we got in the car and made the 10 hour drive to Rhinebeck. Just in time to catch a great house concert by Mile Twelve and meet the other members of the band for the first time. 'very nice people, all. We did the customary exchange of T-shirts and other swag but David was the first to don one of the offerings and had this photo taken to prove it.

Not to be outdone, I decided to wear my Mile Twelve shirt while high in the air in an open cockpit bi-plane.

That's me just before boarding a 1929 New Standard D25


Here's a couple of shots taken high above the Hudson Valley.


For those of you flight enthusiasts, heres a video of our flight that day.


Well that's all for this month's blog post. Now back to work getting ready for the IBMA (International Bluegrass Music Association) trade show at the end of the month in Raleigh, North Carolina. If any of you are planning on attending, please stop by to say hello. We will be in booth #307 right beside Bourgeois Guitars.

I love it when life hands you a peach! A couple of weeks ago, two old friends of mine contacted me and wondered whether I'd be interested in spending a day with a 1924 Lloyd Loar mandolin (serial no. 76081) with the freedom to thoroughly examine it and document anything we could measure. Well of coarse I had to think about it...................... for about a half second!

The two friends in question were Tim Bellamy, an accomplished player and budding builder who would be bringing the borrowed mandolin to the "inquisition" and Mark Schnurr, a highly regarded violin and mandolin maker whose well equipped shop would serve as the examination room. Here we are, the three of us.

Since Tim was voted the official photographer, I had to use an old image of him and I that was taken back in 2004. Tim hasn't aged a bit, me, well, let's say the hammer of life has struck a few blows.

One of the first things we did of course (after much gawking) was to measure the thicknesses of the graduations. We decided to make the measurements in a pattern of expanding circles radiating out from the center of the plates. This, we reasoned, would be most likely to show any intentional patterns in the thicknesses. To accomplish this, strips of 1/4" tape were applied to the plates in a spoke like pattern with the hub at the center of the arch, or in case of the top, the center of the bridge location. The strips of tape were then marked with equally spaced lines to locate the points of measure. While Mark manipulated his electronic thickness caliper, I read out the numbers and recorded them on a special form.

In addition to measuring the graduations, various tap-tones were recorded ( the main air resonance was measured to be near a D4 which is quite typical of Loar signed mandolins), archings were mapped and measured, f-hole rubbings were made, a Saunder's type loudness curve was plotted and a casting of the back plate was made.

In summing up, a wealth of experience and knowledge was gained, while in the company of two long time friends that I don't get to see often enough. It was so kind and generous of them to include me in this extremely rare opportunity. Speaking of generosity, we all owe a great debt of gratitude to the owner of this rare Lloyd Loar signed mandolin. Thank you so much for letting us have such and intimate look at this historic instrument!

Until next time,

I've been very busy lately finishing up orders for a "Studio-A", a "Vanguard" and a "Yorkville" jazz model mandolin. I'm happy to say that those are all completed and ready to ship to thier awaiting customers. This week, I got off to a bit of a late start on two more F-models, one "Classic" and one "Grand Classic". I put together this video fairly quckly while using my pantographic carving machine to rough out the tops and backs. Specifically, the video below shows me roughing out a top plate. I leave the plates a little over-sized to allow for final carving by hand.


Until next time,

Something a little different for this month. A Vlog!

This month I present a video of how I approach the French polishing of one of my mandolins. This is part 1 (the bodying sessions) but I'm not certain that I will have the time to do part 2 which I call the polishing sessions.

Warning: This video contains subject matter that , unless you are among the most ardent of mandolin nerds, could bore you to death. Viewer descretion advised.



Until next time,

Recently, the good folks at Schaller sent me a free sample of their newly designed, GrandTune® mandolin tuners in exchange for my reviewing them and reporting back. Schaller has been using this revolutionary "Velvet-Tec" technology on their GrandTune® guitar tuner series for a while now but they just recently rolled out mandolin sets that utilize this same cutting edge design.

I must say that I was pretty skeptical (as usual) that these tuners would be noticeably better than anything I have seen on the market up until now. After all, at it's core, a tuner is just a simple worm and cog gear mechanism but after holding a set of these little marvels of engineering in my hand, all that skepticism quickly evaporated. In my opinion, these tuners are real "game changers".

They start with a relatively simple and elegant design re-think and then carry it out with the highest quality materials (such as their new formula "bell brass" bushings) and "hyper-accurate" machining of gear joints and fittings. No fancy polymers or other coatings are used to achieve the high level of lubricity, rather, the high quality alloys provide the silky smooth performance with nothing to wear off or degrade over time. Schaller is so confident that these tuners will function trouble free for generations, they have permanently locked, covered and sealed all the screw joints for a lifetime of maintenance free performance.

As I held these tuners in my hand the first time, I grabbed hold of the string posts and worm shafts to check for the amount of play by applying lateral pressure to the components. To my astonishment, the play was zero! They felt as rock solid as if they had been welded together but turned with a smooth yet solid feel, like steering a Porsche. This complete lack of play, not only assures that the worm and cog remain in perfect alignment, it also prevents any sympathetic vibrations and rattles to absorb sound energy and create undesirable noises. I think that part of the the reason these tuners are such high quality, is that unlike most brands of tuners that have gone to lower cost off-shore countries to manufacture their tuners, Schaller still makes all of these GrandTune® machine heads in house at their facility in Bavaria, Germany.

I'm sure this all reads like paid advertisement for Schaller but I assure you that aside from receiving one free set of tuners, I have no financial remuneration from Schaller. It's just that I am so pumped about these tuners. I have been wanting high end tuners at a fair price for decades, to match my desire to offer the serious musician the highest quality instrument possible.

In that spirit of wanting to offer my customers only the best, I have decided to make Schaller GrandTune® tuners my standard tuners going forward and I'll absorb the extra cost in order to hold my prices at the current level.

Until next time,

I'm a little late for this month's blog post. I've been extremely busy the past month. I have several new projects on the go along with my usual schedule of building mandolins. I won't disclose what those projects are at this time but I plan on making some exiting announcements later this year.

Currently, I am working on two customer ordered mandolins. One is a Vanguard model F-style and the other is a Studio-A. I spent the day applying the binding to the pegheads of these mandolins and I thought I'd give a brief overview of the process. In the past, prior to my temporary absence from luthiery, my pegheads were straight sided and uniform in thickness. Binding them was a matter of routing a ledge (rabbet) around the perimeter and applying the various sections of binding. Since re-starting my business, I have re-worked nearly all of my molds, templates and methods to much more closely capture the outward ascetics of the mandolins of the 1920s. As a result, my pegheads are now tapered in thickness and the sides are cut at an angle to the peghead face. For this reason, the rabbets for the binding cannot be cut with a basic router set-up as the pilot bearing will not follow the twisting contours of the peghead shape.

There is no real practical purpose for angle cutting and tapering the headstock. It is purely a more esthetically pleasing way of doing things. We humans like to see shapes that resemble nature and in the natural world, there are few straight and uniform shapes. The subtle twisting and tapering of the peghead lends it a much more organic vibe that is just easier on the eyes. I have to stand in awe of the designers of the Lloyd Loar era mandolins in that they did not take the easy way out. No, they were truly intent on creating not only a new design, but one with as much or more refinement as was reached with violins over 200 years prior.

In order to achieve this easily overlooked detail, the headstock veneer plate is cut to shape and binding applied before the peghead is given its final shape. In the photo below, (sorry for the poor focus) I have glued the pre-shaped peghead veneer to the peghead face and rough trimmed the peghead, leaving it oversized enough to apply the binding to the sides of the veneer.

The celluloid binding is heated just enough to make it pliable and then shaped to the various sections of the peghead profile, in this case, an A-model. If the binding scheme is to have strips of contrasting lines (purfling), then the joints must be painstakingly mitered to create the effect of a continuous line, or lines, framing the headstock. Simple butt joints were used where the binding had no purfling strips. The miters can be cut with a razor sharp chisel as in the photo below. Note that you can see in the reflection of the highly polished surface of the chisel, the resulting angle of the miter to be cut.

Note angle of miter reflected in the chisel face.

Once all the sections of binding have been glued into place and the glue has dried, the top faces are scraped flush to the peghead face.

After that, the sides of the peghead are sanded flush to the bindings using a fixture that holds the fingerboard surface of the neck blank horizontal to the perpendicular orientation of the spindle sander.

The result is a gently twisting contour to the peghead sides.

I believe that it is attention to subtle details such as these that separates a good instrument from one that is truly first class.

Until next time,

Mandolin bridges must be fitted very accurately to the contours of the mandolin's top. Any gaps in the fit will decrease the efficient transfer of the string's vibrational energy to the top of the instrument resulting in a loss of volume and richness of tone. The traditional way of achieving a perfect mating surface on the bridge feet is to fasten a piece of sandpaper to the top, in the area of the bridge and then to rub the bridge feet back and forth (some use a side to side motion) until the bridge base conforms perfectly to the mandolin top. Until very recently, I have always held onto the bridge by hand while performing this task and achieved very good results. It is extremely important to hold the bridge in a consistent, vertical or slight back angle while moving the bridge across the sandpaper in order to ensure that the base has the correct concave profile.

With the introduction of my new J - series of jazz mandolins with their more twisting compound curves, I decided to make life easier for myself by constructing a little jig that holds the bridge in perfect orientation while I move it back and forth across the top. I didn't come up with the idea for this jig myself. This type of fixture has been used by arch-top instrument builders for many decades and there are a few different versions of these available from various suppliers. After looking at the available bridge fitting fixtures, I decided to make my own incorporating and modifying the elements that I liked best.

As you can see below, it is a very simple jig that uses the bridge base's own screws and thumb-wheels to secure it in place. A small ball bearing, lifted from an old router bit serves as a roller wheel and creates a stable three point contact area. The wheel height is adjustable via a small thumbscrew, allowing the correct bridge angle to be securely set.

In use, the jig is grasped with both hands and rolled back and forth with very short strokes about 10mm in total. That is, 5mm forward of the bridge's ideal location and 5mm behind.

When ebony dust from the bridge base can be seen across its full length, the bridge is properly mated to the top. Each bridge must be carefully fitted to the particular mandolin it will be used on.

Just to be absolutely certain of a tight and solid fit, I like to create a very small hollow in the bottom of the bridge feet, about .002" deep, using a curved scraper.

The photo above shows me scraping the very slight hollow in the bridge feet. This will ensure that the perimeter of the base will be solidly seated to the top for maximum coupling and energy transfer.

Here's a look at the completed fit.


Until next time, thanks for reading,

My apologies for skipping January's blog post completely. With all of the extra holiday preparations, I got a little overwhelmed. On to this month's topic. French polishing.

The art of French polishing is shrouded in much mystique and sometimes, especially in the past it was even guarded with secrecy. As I mentioned in an earlier post. I was late to the whole varnish finish revival. I am by nature quite skeptical and I was heavily invested in my lacquer finishes, both in time to acquire the skills and in the spray equipment. When I finally turned my attention to investigating the claims that people were making about "varnish" finishes, I was quite surprised to find that there are much better finishes than lacquer in terms of sound and also neck feel. The first mandolin that I completed after teaching myself the art of French polishing was noticeably more "open" in it's sound. I knew in an instant that I could never go back to lacquer if I wanted to stay committed to pursuing the highest level of tonal excellence.

This revelation, by necessity, opened up a whole new area of research, experimentation and the acquisition of new skills. One big question that I now had was, which type of varnish or combinations of varnishes was the absolute best for sound quality? Finding the answer to that was a long road of researching varnish recipes and application techniques and then trying them out to hear the results. I tried various oil varnishes, French polish over oil and spirit vanish alone, applied by French polishing. No matter what I tried, I always came back to straight spirit varnish, applied by the French polish method. It's not that the other finishes produced bad results, Good results can be had from oil or even lacquer but the standout best for me was always a spirit varnish. In case you didn't know, the term spirit varnish refers to a finish that is dissolved in alcohol and dries by evaporation of same. Shellac is usually the main ingredient in spirit varnish but it can also be based on other natural resins or gums.

Spirit varnishes based on shellac are often modified with small amounts of other resins and gums such as sandarac, benzoin, mastic and copal. These additives can modify aspects of the shellac such as hardness/softness and toughness. Since it takes many hours spread over months and years to perfect a varnish recipe, many instrument builders, including myself, do not like to divulge the exact varnish recipe that they are using. Suffice it to say that I use a proprietary shellac based spirit varnish.

The other equally important aspect of finishing (perhaps even more so) is achieving a thin film thickness. This is where French polishing is unequaled. It must be understood that French polishing is a technique and not a particular varnish. It is a method of applying a finish in vapor thin layers that fuse with prior and subsequent layers and that can only be done with spirit varnishes.

In it's simplest form, French polishing requires three things, spirit varnish, a little oil for lubrication and an applicator referred to variously as a fad, menuca, tampon or rubber. I use the term fad as it sounds the least offensive and no one giggles every time I say it.


Pictured above are basic materials used in French polishing.

A jar for storing the fad between "sessions", spirit varnish, alcohol, the fad and some oil.


The fad is made up of an absorbent wad of some natural fiber wrapped with cotton linen which is pulled tight to remove any wrinkles. I have tried various wadding materials like old (clean) wool socks, cotton batten and felt. My favorite at this time is diaper cloth. The wrapper can be made out of an old (white) cotton tee shirt or cotton linen. My preference is cotton "trace cloth".

To get started, the fad is loaded up with some spirit varnish. The amount of moistening is very critical and can only really be learned through experience. I think that one reason for the mystique around French polishing is that it can only be explained so far, the rest has to be gained through practice and experience. I keep some white paper handy to blot the loaded fad on so that I can see how much varnish it is depositing. You want the fad to leave a cluster of small splotches on the paper rather than a real wet spot. When the fad is properly loaded, a very small amount of oil is added. I make a small smear of oil on the back of my left hand to tap the loaded fad onto in order to pick up some oil. Shellac is extremely sticky and without the oil, you run the risk of having the fad stick to your finish and pulling off some of the film that you worked so hard to build up. Knowing exactly how much oil to add is again, a matter of experience but it is not much. Now your ready to French polish!

It is important to know that once the fad makes contact with the surface it must be kept in constant motion until it is raised off the surface. Some people describe the initial approach as like an airplane coming in for a landing. Once on the surface, the fad is kept moving in a variety of patterns such as circles and figure eights. When done, the fad is lifted off the surface like an airplane taking off. In French polishing, there are no "coats" as in spray finishing. Instead there are "sessions". The first sessions are often called "bodying" sessions as the fad is loaded with the full strength varnish solution and the idea is to build up a film thickness relatively quickly. As the sessions progress, more alcohol is added to the fad to thin out the varnish and create a beautiful, crystal clear, high gloss. When the fad is loaded properly, a very thin visible trail can be seen behind it while it moves around the surface. This trail, if of the proper dampness, will start evaporating almost immediately after it goes on. In this way, vapor thin layers of varnish are put down. The term layers is not quite right because the varnish will fuse to the existing finish and become an integral part of the overall film.


The first sessions of French polishing to build some thickness.


As the vanish is laid down, it does not dry fully and after some time the surface will become too soft to continue without doing more harm than good. This is when the mandolin is put away for sometimes hours and sometimes overnight. Again, experience is the guide. Because the mandolin is a relatively small object, the finish becomes soft fairly quickly after being repeatedly rubbed with the moist fad. The finish must be built up through many short sessions. Generally about 20 minutes each.

Here's the beauty of the French polish method. The gloss forms itself without any need for sanding and buffing out. That means that as soon as you have achieved a pleasing finish you are virtually done. In spray finishes, you must allow for sanding back the finish for final buffing. This means that extra "insurance coats" are sprayed in order that it can be safely sanded back with minimal risk of sanding through the finish and into the color coats and still have enough finish left for aggressive buffing out.This is why the French polish method can produce such a thin film. As soon as the finish becomes glossy, you are done so the least amount of material is needed. The depth and clarity of the spirit varnish is noticeably superior to any lacquer and therefore can create the illusion of a deep finish while in fact being very thin.

As the polishing progresses, more and more alcohol is added to the fad along with some varnish and less and less oil is used. (experience is the guide) until the surface is left with a crystal clear, yet glowing finish that is far superior in both beauty and tone than any factory applied spray finish. This is the advantage of the independent builder. Not concerned with shareholder profits or recouping investments in expensive machinery and tooling, the independent luthier can use only the best materials and methods to create an instrument of the highest possible level.


It is a true wonder to behold when after hours of hand rubbing

the superior depth of a French polish finish emerges!

Mandolin necks are under a great deal of tension. A typical set of strings tuned to pitch will exert about 160 lbs. of pull. (Picture a full grown man hanging from the strings.) Since the majority of players prefer a fairly slender neck, makers have devised various ways of reinforcing the wood of the neck in order to satisfy these needs. The tension exerted by the strings causes the neck to want to bow forward, toward the bridge. A very small amount of bow, often called relief, is actually more desirable than a completely straight fingerboard surface. This is because the strings vibrate in an arc and by having a small amount of forward bow, the string height above the frets, or action, can be set to its lowest possible height without causing string "buzz". A low action in turn, also minimizes the leverage on the neck, exerted by the strings and so also aids in reducing unwanted forward bow.

The original F-5s of the 1920s utilized a single truss rod system in order to stiffen the neck and introduce some adjust-ability of the amount of neck relief. While the design that was used did work to some extent, it did also have some inherent flaws that later stringed instruments gradually improved upon.

One of the flaws in the design is that when the adjusting nut is tightened, it creates a compression force on the neck which has little benefit to the amount of bowing but can lead to other problems such as neck twisting. The other main flaw is in the particular design that was used on the Loar era F-5s. On those instruments, the rod was installed with an arc that was highest in the center of the neck. Since, as the adjusting nut is tightened, the effective section of the rod becomes shorter and thus the rod wants to become straighter to eliminate the excess length caused by the arc, this design can be counter productive. If you look at the drawing below, you will see that in the way those early mandolins were done, this would mean that the neck would actually want to bow further forward instead of counter-acting the force of the strings.

Drawing of Loar era single truss rod. If the rod becomes shorter by tightening the adjusting nut, the rod will want to straighten out causing a forward bow of the neck while also adding a compressive force to the wood of the neck.


In my mandolins, I utilize a more modern design, "double rod" system. It consists of one rigid, non-adjusting square steel rod with a round steel rod welded to it at the tail end and an adjustable nut at the other. I did not design this rod myself but it is, for my purposes, the best design I have seen for use in mandolin necks. It can fit into very slender necks and the adjusting nut ends up in the same location as the original F-5s allowing for a traditional look. I have these rods made to a custom length by Luthier's Mercantile International in California. Here is one pictured below.

As you can see by the photo, the rods are welded together at one end and at the other end is an adjustment mechanism for the lower rod. By tightening the nut the lower rod it is effectively made shorter. This causes the upper rod to arc over backwards. Just adjusting the rod until it is snug will create a very rigid reinforcement in and of itself much like a solid non-adjustable steel bar would be. This is how the rods are adjusted when I initially string up a mandolin for the first time and there is rarely a need for any further tightening.

The other great advantage of this system is that it is completely independent of the neck wood itself and therefore does not add any unwanted forces to the neck.

For the rod to work at its best, it must however, be properly and accurately installed. It must fit tightly in its routed cavity. Luckily this is not too difficult to accomplish. I use a round nose router bit that is the same diameter as the diameter of the rod to create a channel that is 2mm deeper than the rod is tall. When the rod is installed, a filler strip of wood is glued in over the rod with clamping force to assure a completely snug fit. Here is a cross section of a neck, at the heel, showing how snug the rod is embedded in the neck.....

Note the filler strip above the truss rod.


....and here's one of a routed neck blank along with a truss rod.


Below is a drawing of how the double rod is installed in one of my mandolins.


One other detail that is not overlooked is the possibility that truss rods have of developing a very annoying rattle when certain notes are played. While installing the rod very snugly goes a long way to prevent this, I go one step further and apply some silicone rubber between the two rods. Then, just before the rod is permanently installed, I also apply a bit of silicone rubber to the bottom of the truss rod channel thus eliminating any possibility of a rattle developing down the road.


In my approach to building mandolins, I have a huge reverence for the great instruments of the past but I am not dogmatically closed to the possibility that there are still areas where further refinements can be made. The original truss rod design, I believe, is one of those areas.

The "Wabash Cannonball"


November 3, 2016

After 40 years of bending the sides for my instruments over a hot pipe, I have moved into the steam age! I finally got around to making a side bending fixture that utilizes steam to pre-soften the wood for the rims. The impetus for this was the introduction of my new Jazz models or as the youngin's like to say J-models. Bending the scrolls for an F-style mandolin by hand over a hot pipe can get quite intense. A liberal mixture of experience and patience is required to get the side to fit perfectly in the form for consistent results. It is not uncommon enough to spend an hour or more on just the right curve of the scroll only to have it break apart in your hands when you are nearly done. (I have been known to mutter expletives such as 'fiddle dee dee' or 'peanut brittle' after just such an event) I don't know what on earth I was thinking when I designed the cutaway for the Jazz models but I clearly wasn't thinking of the practical limits of bending wood over a hot pipe! Actually, I wanted a cutaway that had the look of the classic Jazz guitars of the 40s and I wasn't willing to compromise with an easier design. The tightest curve of the cutaway ended up about twice as tight as the already skill testing F-5 scroll. So, how was I going to accomplish this?

I decided to try steam. After all, this is what I am lead to believe was used to bend the sides of the original F-5s of the 1920s. Turns out that it can work quite well once I refined my technique and made a decent bending fixture. Below is a photo of the simple steam box that I put together. Steam from a small steam generator is introduced through a hose at the back end of the box (right, in photo) and a small vent whole is drilled in the hinged door to allow the steam to travel the length of the box.

Once softened with the steam, the side is removed from the box and placed on the bending form where it is clamped into place and the excess water driven out by the use of a commercial heat blanket. The photo below shows the fixture in action bending the tight curves of my cutaway Jazz model.

Since I had made the fixture to bend the sides of my Jazz models, I took advantage of the steam technology and made a form for my F-styles as well. I should have done this a long time ago. This method creates beautifully consistent curves and an increase in overall quality.

One drawback is that (all gains are accompanied by some loss) this method creates a heck of a lot of steam! So much so that the humidity levels in my shop shoot up from 40% RH to 60% in less than an hour. During the colder months, when I'm heating the shop this takes less than a day to get back to 40%. I suspect that during the hot and relatively humid summers here, I will have to take this apparatus outside to do my bending or cause my dehumidifier to run overtime!

Well, we just drove in from the IBMA Trade Show and boy, is my butt sore! We were sitting in the car for 14 hours straight!

I'm a little late in writing this post as I am still tying up all of the loose ends and sending thank yous and greetings to all of the contacts that we made while down in sunny Raleigh, North Carolina. The trip got off to a slow start as we were held up at the border for 7 hours while we got the proper paperwork to bring in three mandolins valued at over 20,000.00 US dollars. You see, in my defense, the last time that I attended the IBMA trade show in 1992, I just told the nice border guards what I was doing and where I was going and they said, 'that's great. enjoy your trip.' Things are a little different today and I should have been better prepared. I will be, next time.

Anyway, it was a beautiful drive down through the mountains. The folks are very friendly and helpful to strangers. We met so many nice people at the show. There are too many to mention all by name. My wife Jody was in charge of taking photos so of course I packed the camera with various lenses, filters and even a tripod. What I didn't pack was an SD card, which rendered the camera useless. Very fortunately for us, the booth next to ours, Bourgeois Guitars, was manned by one of the most friendly and helpful guys you could ever imagine. James Cook was his name and hospitality was his game. James quite kindly offered to lend us his cell phone so that Jody could take photos of some of our visitors and he then uploaded them onto a photo sharing site where we were able to retrieve them. THANKS BRO! (We also learned that we had an endorser in common. Dan Tyminski endorses and plays Bourgeois guitars as well as Apitius mandolins.)

A few of the other people we met were David Benedict (a brilliant young mandolin player based in Nashville TN), Kym Warner (born in Australia now residing in Texas with 3 Grammy nominations under his belt, a member of "The Green-cards" and a solo album, "Everything that Brought Me Here"), Elijah Moore, a very young mandolin player with awards under his belt! (watch for him) J. P. Cormier, a fellow Canadian dropped by several times (more on that later)

Again there were way too many to mention all by name but we enjoyed meeting you all!

Before the show, I custom shaped 600 guitar picks and offered them for 25¢ or 3 for a dollar (bluegrass math?) but in fact, we intended all along, to hand them out for free, which we did and they seemed to be really well received.

One of the big draws to our booth was the new jazz model mandolin, "The Yorkville". J. P. Cormier came by with very kind words for my mandolins and started to tell me that there was this store, up in Canada, The Twelfth Fret, that sometimes carried an Apitius mandolin. Turns out, he knew of my work for years and didn't realize that I also was Canadian. Once J.P. got that jazz model in his hands, well, love at first sight comes to mind. J. P. was at the show representing Boucher guitars. 'High -end guitars from Quebec. He is such a warm and unassuming guy and "that boy can play."

Kym Warner of the Green-cards was also very enthusiastic about the jazz model. The Green-cards had not been on my radar until I met Kym but they definitely are now.

We were also honored by a visit with David Benedict. David is a very talented player who is currently playing mandolin with Missy Rains and the New Hip. David really liked the new "Vanguard" f-model that I brought along. So much so that we set up a private test drive in a more acoustically friendly environment. (I think there may be a new Apitius in his future!)

Again I would like to say thank you to all the wonderful people we met. I spend most of my days alone in my shop and it sure is a shot in the arm to meet so many people who appreciate what I do in there.

'hope to see you all next year if we can make it.

The term "hand-made" is difficult to define. I think the majority of us would not consider a modern, mass produced automobile to be hand-made even though some of the various components are bolted, screwed or snapped into place by real human hands. Where then does the legitimate use of the term hand-made begin? I've heard some people argue that a computer guided router (CNC) is "just another tool". Still others have said that if any tools are used, then an object is not technically made by hand and so the term hand-made is completely meaningless. But if the term is meaningless, why do so many producers of goods use the term? I think it is because most of us have an image of what it is to be made by hand as opposed to mass produced and these manufactures want to evoke that image in connection with their product.

I can't clearly define the term hand-made. I think that there is a fairly wide gray area that comes down to the subjective opinion of the individual. I do however, believe that my mandolins can truly be called hand-made with very few who would seriously argue the point. One person, starting with raw materials then making all of the constituent parts using a combination of hand tools and basic woodworking machinery, then assembling those parts one or two at a time with hot hide glue and finally, applying a proprietary spirit varnish of natural resins with a hand held wad of cloth known as a "fad" most certainly qualifies Apitius mandolins as hand-made.

Is hand-made better? Not necessarily. Without a high degree of skill, knowledge and experience, a hand made thing can be more aptly termed "home-made". ( I won't get into defining "home-made" but I think you get my drift.) Instruments made on a production line can be quite good and if not really good, certainly good for the money, but to get to the very highest level, I believe that making by hand by a dedicated and skilled craftsperson is still, and will probably always be, the absolute best method for true excellence.

A dedicated and passionate artisan can take the time to use all of his/her senses when constructing the instrument. In the world of instrument making, the only way to make gains in sound quality and playability is to pay close attention to the very slightest of details. Getting one or two details right will often not be manifested in a noticeable improvement in sound quality but the accumulative affect of getting many details right will. As an independent luthier, I can, and do, take time to feel, flex, tap and smell the wood I am working with. When I am tapping a top or back plate to listen for it's response, my shop is quiet. There is no din of other workers running machinery. I can focus intently on the sound.

Making by hand also results in truly unique instruments. Each one, while having the characteristic voice of an Apitius mandolin, also has its own individual character. For example, the way I arrive at the mandolin's neck profile is by carving it down by eye and then after the instrument is put together and the fingerboard glued on, I feel the neck with my hand in a manner so as to imagine playing it. I then make fine adjustments with rasps and sandpaper until I feel that the neck is very comfortable for playing. I believe that subtle details like this is what separates very good mandolins from something extraordinary.

Binding is one of those things that can be a little confusing for someone who has not researched the topic at length so today I thought I'd give a little primer on binding as it applies to fretted instruments. To start at the beginning, binding is the strip of material, typically about 1/4" wide, that is inset at the edges of the instrument. It can be made of varying materials but is most commonly some type of plastic or wood. For the past 100 years, the most common material for binding on fretted instruments has been celluloid nitrate plastic that is made to resemble ivory. It is known as "grained ivoroid". It consists of alternating shades of ivory that form stripes in the material to imitate the grain found in genuine ivory. (I do not use any real ivory in my instruments) Wood bindings and other types of plastic bindings are also not uncommon.

The main purpose of bindings are to protect the vulnerable edges of the instrument from accidental bumps and knocks. The top of the instrument is especially vulnerable as it is made from relatively soft spruce. The binding is inset into the edge of the instrument and as it is made of a harder material, is better able to withstand minor knocks. Some builders say that the binding also, or even mainly, is there to seal off the end grain regions of the top and back plates. I can see no reason that the binding would be any better at this than the finish, be it some type of varnish or lacquer.

Another function of the binding is decorative. The binding, which usually has a contrasting color to the instrument, helps frame and define the shape of the instrument. In addition, it is quite common for makers to add additional thin strips of material to the binding solely for decorative purposes. These thinner strips of contrasting colors are called "purfling". On mandolins, you will quite commonly see these black and white purfling lines on the top surfaces of the plates. This is often referred to as "top bound". I find the term a little inaccurate as it would be more accurate to say "top perfled" . This same configuration is also referred to as "triple bound top". Which is technically more accurate than "top bound". I'm not about to try and stem the popular nomenclature for the different types of binding options on a mandolin so I have also come around to using the term, top bound. It does simplify conversations between those up on the lingo but it can be a little confusing for the novice.

Here is a photograph of a "top bound" mandolin body along with a photo of an actual binding strip of grained ivoroid laminated to black and white purfling strips that create the "top bound" effect.

"Top bound" body

Next is a photograph of a "side" bound body and a photo of an ivoroid strip laminated to black and white purfling strips to create the side bound effect.

"Side bound" body

Grained ivoroid binding strip with black/white purfling lines for side bound effect.

The next photo shows how the edges of the body are routed to accept the binding strips. This type of routed ledge is called a rabbet. Note: The scroll area cannot be accessed by a conventional router and so I cut this section with various hand tools.

The binding strips are first softened with heat and then bent into the shape of the body contours. They are then glued into place with a special glue that partially melts the binding and fuses it to the wooden body of the mandolin.

Once the glue has dried, the bindings will be scraped flush to the body.

Much of the difference in my F-style mandolin models is in the style of binding. The famous Lloyd Loar era mandolins of the 1920s were bound in different ways at different times and my models reflect the main binding schemes used in those instruments. My "Vanguard" model has binding very similar to the early F5s, with side bound neck and peghead and a top bound body. The "Rosine" model is side bound throughout as were a small number of F5s in the July 9, 1923 batch. Most notably, one of those was the favorite mandolin of Bill Monroe the "Father of Bluegrass". My "Classic" model is top bound throughout as was typical of the later period 'Loars. I occasionally make mandolins with both side and top binding. No Loars, to my knowledge, where ever done this way. I call these mandolins my "Grand Classic".

In today's blog, I'm going to do my best to demystify the relation of wood to humidity. I'll start by describing what we mean by terms like humidity and relative humidity. Humidity is a term for the amount of bound water molecules in the air. If you measured the amount of water in a defined volume of air, say a cubic meter, without regard to temperature, that would be the absolute humidity. (usually expressed as grains per cubic meter) In the real world, what is important is the relative humidity and not the absolute humidity. Relative humidity refers to the amount of water molecules that can be bound in the air at a given temperature.

The warmer air gets, the more water it can absorb. Relative humidity means, the amount of actual water in the air relative to the maximum amount of water that the air could hold at that temperature. So for example, if we have a volume of air with an amount of bound water in it that is equal to 50% of how much water the air could hold at that temperature, it is said to be at 50% relative humidity or, commonly abbreviated to, 50%RH.

Now, if we take that same volume of air and heat it up, it now has the ability to carry more grains of water but if the absolute amount of bound water remains the same, then the relative humidity will drop because it now has less than 50% of the water that it potentially can hold. This is exactly what happens in the winter months. The outside air is cold and say, at 50% relative humidity then we heat it up with our central heating and unless we are adding moisture to the inside air, the inside air drops in relative humidity. It is not uncommon for heated homes and apartments to get down to 15%RH (worse than desert conditions) if humidity is not added to the inside air.

Now here's how this relates to your wooden instrument. Wood, all wood, is hygroscopic which is a fancy term for saying that it picks up or releases water depending on the relative humidity of its surroundings. If the relative humidity stays steady at a given amount then eventually the wood will reach an equilibrium moisture content (EMC) with its environs. The exact moisture content (MC) of wood in equilibrium with a given RH will vary somewhat from species to species. The various spruces used in making stringed instrument soundboards will generally have an actual moisture content by weight of 7% when in equilibrium with a relative humidity of 37-40%RH. Problems arise because as wood takes on water it actually increases in size and as it gives up water or MC, it actually shrinks. This is a property of wood and remains a property of the wood as long as the wood is still wood. We cannot change that. What we can do is learn how to deal with that fact.

Imagine a spruce mandolin soundboard being glued to a rim in an environment of 40%RH. The soundboard is measured at say 250mm across at its widest point. Now the instrument is completed and is sold to a customer who takes it home in the winter time to his heated home. If that home is not being humidified and has gotten down to say 15%RH the soundboard will now start to release moisture which will then cause the soundboard to shrink. Going from the 40%RH at which it was built to 15%RH in a heated home will cause an actual shrinkage of the soundboard in excess of 1 full millimeter. The problem is, the rim does not change in diameter, in any significant way, which means that the shrinking soundboard, which is glued to the rim, feels itself under tension and somethings 'gotta give. Either a crack develops in the wood to relieve the stress or a seam lets go.

In the summer, when the humidity goes up beyond the 40%RH that the instrument was glued together in, the wood swells in size. This time, though the rim is holding things in place, the soundboard does have somewhere to go. It can bulge up causing the string action to rise. Although the soundboard does have some room to maneuver, there is a limit and if the RH gets too high, the stress caused by the expanding wood will typically lead to seams letting go. Since high humidity is very often associated with high temperatures, these conditions will also weaken glue joints while putting the stress of the expanding wood on them. In actual numbers, a spruce mandolin soundboard that was glued up at 40%RH will grow by nearly 3mm when at an equilibrium with an environment of 80%RH

The key to avoiding problems caused by excesses and extremes of humidity is to keep your instrument from being exposed to these extremes. Solutions for excessive dryness include using a whole home humidifier on your furnace, using a room sized humidifier in the room where you store your instrument or using a humidifying device in a case in which you store your instrument. My preference is in using a whole home humidifier. It requires the least amount of ongoing maintenance and is good for the human occupants of the home as well. A room size humidifier can do a good job if correctly sized and maintained. Using a device in your case is my last choice. I find that these require a lot of maintenance and monitoring. It is difficult to insure that your are adding the right amount of moisture and not overdoing it.

Here comes one of my real pet peeves and that is that the typical hygrometers you buy at the hardware store are very often very badly calibrated. It's OK for me, I have sling psychrometers to calibrate my hygrometers because it is my business to maintain proper humidity levels but it is not so good for the average person. Proper calibration of your hygrometer is essential in maintaining proper humidity levels in your home. Other wise you could be lead to believe that you are maintaining the the proper level, which by the way is 40 - 50%RH, when in fact you are not. I wish I had a good answer for this. Here in the Toronto area, I know of one music store, The Twelfth Fret, that will calibrate your hygrometer for free if you bring it in. Maybe there are other reputable shops in your area that will do the same for you.

So the main takeaway is, keep your instrument at a comfortable humidity level, avoid extremes and you will be able to pass it along to your grandchildren in perfect working order.

Here is a handy chart that I drew up. It plots the equilibrium moisture content of a typical spruce species vs relative humidity and also shows the actual dimensional change that occurs across a 250mm wide mandolin soundboard. Keep in mind that the maples used for the back actually have a larger coefficient of expansion than the spruce top. This is even more so in rift-cut and slab-cut backs which are popular for their figure.

Varnish is much talked about yet widely misunderstood in mandolin circles. You will often hear someone say, "This mandolin has a varnish finish." or "Is that mandolin varnished or lacquered?" One of the misconceptions starts with the meaning of the term, "varnish". Merriam Webster defines varnish as;

a: a liquid preparation that when applied to surface dries to form a hard lustrous typically transparent coating
b: a covering or glaze given by the application of varnish
c: (1) something that suggests varnish by its gloss (2): a coating (such as deposits on an internal combustion engine) comparable to varnish

As you can see, the term varnish does not specify any certain material(s) but rather any coating that is transparent and lustrous. A mandolin manufacturer is free to call a nitrocellulose lacquer finish "varnish" as lacquer is actually a type of varnish. (I have also seen claims of "Hand-applied lacquer". I guess that means that a human being held the spray gun, but I'll delve into the meaning of "hand-applied and "hand-made in a future post)

Personally, I have always thought that the bottom line is, how does the resulting instrument sound? As a musician, sound and playability should be the overriding concern. If one instrument is lacquered and sounds better to you than another-one that has a "varnish" finish, then, for the most part, you needn't fret over the composition of the varnish. A "varnish" finish cannot make an inferior instrument sound better than a superior instrument with a well applied "lacquer" finish. What I have come to believe, through, personal experience as an instrument maker, is that the best finish will "get out of the way" of the instrument's sound. I also refer to this as being "acoustically transparent".

By nature, I am a very skeptical person. I like empirical proof of a claim. In the case of the importance of one type of finishing material over another, I thought for years that this was probably more marketing hype than anything substantive and so I put trying different finishes at the bottom of my list of experiments aimed at refining my sound. In my defense, early in my career I visited a large and respected guitar manufacturer where, among other things, it was explained to me, how their nitrocellulose lacquering process was a marvel in achieving a superior sound. I then spent a good deal of time learning and perfecting my method of applying a spray lacquer finish so I felt no need to change things in that regard but after years of hearing talk of the benefits of "varnish", I decided that it was time for me to prove to myself, one way or the other, if there was anything to all the hype.

To make a long story a little shorter, I spent hours and hours researching and learning the art of French-polishing and when I felt confident enough to finish a mandolin this way, I was very impressed with the results, to say the least. The mandolin just had an openness and vibrancy that I had never heard in a brand new instrument before. In addition, it had a great neck feel, as if it had talcum powder rubbed onto it. My lacquering days were over! Other benefits included no more breathing in toxic chemicals and feeling much better about my environmental footprint. The ingredients in shellac, which is used in French-polishing, are completely non-toxic and sustainable. The principle ingredient, shellac, is a natural resin secreted by the lac bug. It is edible and is used for such things as pill coatings and candy coatings in the food industry. The solvent used is pure ethyl alcohol, which is the type found in beer, wine and spirits and so it is also completely non-toxic in small quantities.

Of course, now that I am a convert to the crucial role that the finishing material and method plays in the ultimate sound of the instrument, I am continually striving for the best possible varnish recipe. I have done many, many experiments and tests with different oil varnishes and different spirit varnish recipes. Perhaps I'll post my conclusions and thoughts on the oil vs spirit varnish debate another time.

Thanks for reading,
