Varnishing and Assembling the Commissioned 5-String Viola 

Varnishing and Assembling the 5-String Viola for the Swiss Violist 

Continuing Saga Of Varnishing

To begin with,  I started building a 15-3/4″ five-string viola for a violist in Switzerland.

Simultaneously, I had purchased the European Maple one-piece back, as a solid wood billet, with sides, and neck billet. Additionally, I ordered the  European Spruce front plate blank from International Violin Company in Baltimore Maryland.

At the time when I last posted, I had just begun varnishing the viola and had only applied the yellow base coats of varnish. Obviously,  the intent is that this yellow base will provide the “golden glow” shining from within the subsequent darker-color coats of varnish.

However, as I added increasingly dark varnish layers, the changes were increasingly slight. As noted earlier, the change from raw wood to sealer was obvious. Furthermore, the change from sealed wood to yellow varnish was amazing. But the subsequent steps move more gently into the final iteration.

And Assembly!

To begin with the varnish procedure, I had removed the fingerboard and nut, to allow full access to the front plate for varnish-prep, varnishing and polishing. However, now it is time to replace those parts and begin final assembly.

I installed the soundpost, too, so that the instrument corpus could begin “getting used to” that pressure from within.

Then I re-installed the fingerboard and nut, and scraped the joint to make it completely smooth. Obviously, I will have to retouch the varnish on some of those areas.

What’s Next?

Following this, the next thing will be to install the “Knilling Perfection” (internally geared) tuning pegs.; Afterward, I will continue with final set-up.  I can install the pegs now, but the final set-up will have to wait for the varnish to harden a little more.

Resuming Work on an Older Project: 5-String #19

#19 Back in the White

 

“New” Five-String Bluegrass Fiddle, Begun Two Years Ago

I Began in Good Faith, Years Ago!

Originally, I began this fiddle in 2023, thinking I would “press on” and get it done soon. I had already closed up the corpus, with the dated label inside! But, due to unforeseen circumstances, I had to postpone its completion.

A commissioned instrument interrupted the flow of my “built-on-speculation” instruments. I always move any commissioned work (whether repairs or a new build) to higher-priority. I move them ahead of my usual “build it and they will come” work.

The man commissioned a five-string fiddle on one of my early models. So,  I completed his instrument (#16 on the Chronology page) before completing Instruments #17, #18, and #19.   I had planned otherwise, but it happened.

Slight Chaos!

I had begun all three of those instruments, simultaneously. But I did not realize that, in my array of personal labels, I had somehow skipped #16. When that came to my attention (as I worked on the commissioned fiddle) I felt I had to correct the mix-up. I had no option but to print a new sheet of labels, with a #16 in the mix. Then, I labeled his new fiddle, as though I had built it before the other three. I completed it before the others, though, but instruments #17-19 were still hanging on my workspace wall, waiting for their turn. (Sigh…)

Meanwhile, I had surgeries on my right eye (cataract surgery and corneal transplant) and had to wait for it to heal before I could do much work.

Later,  my beloved wife, Ann, fell and broke her wrist, requiring surgery to repair it. At the same time, I had contracted Covid (finally…my first time!) and could not even go to the hospital with her. Fortunately, our daughter was in town,  with her husband, and they took her to the ER.

By the time all that was over, I had the same surgeries in the other eye. (Yeah, it was a really productive year!)

BUT:  Between all the “setbacks,” I did manage to complete instruments #17 and #18 on the Chronology page. (#18 sold almost immediately…that was nice!)

But then…

Another client called  with a commission: This customer wanted a 15-3/4″ five-string viola. She lived in  Switzerland., and will fly here to take delivery, so I again shunted #19 to “last in line.”

Resuming Work on Five-String #19

I have nearly completed the new commissioned viola. (It will be five-string #20…but it is not yet on the Chronology page.)  So I went back and resumed work on #19.

The work had already been done up to (but not including) the purfling on the back plate.  So that is where I had to begin. Unfortunately, I was still “sneaking in a few minutes, ” here and there, while completing the newest viola, so I neglected to photograph the purfling process. However, if you would like to see that process, here is a link to the purfling procedure for a large five-string viola from five years ago.

Preparing for Varnish

I scraped the entire instrument as smooth as I could get it, then brushed coffee all over the instrument, to raise the grain, and allow me to see areas that still needed work. I repeated this cycle until the grain would no longer swell with moisture, then I sanded it lightly all over, to remove any tiny, unnoticed fibers that might still be protruding. The instrument looked like this at that point.

Mineral Ground

I learned for Roger Hargraves that filling the natural wood-pores with a mineral will help the sound, and it prevents excessive varnish penetration. So, nowadays, I rub Gypsum powder into the raw wood surface, to fill those pores. I mix the gypsum with coffee, which adds a tiny bit of color to the wood, but when the mixture dries, it turns chalk-white, mostly obscuring the grain;

Sealer

After the mineral Ground is fully dry, I gently sand off any excess gypsum, that is sitting on the surface, so that it will not obscure anything once the varnish is in place. It still looks stark white, but does not have piles in the corners, or elsewhere.

The Sealer application always seems like magic, because, as the sealer surrounds all the perticles of mineral,  the gypsum turns transparent. It literally disappears, and will never be seen again!

The Sealer I use is made of rosin, dissolved in a mixture of denatured alcohol and Spirits of turpentine (the one that strongly smells of pine.) It takes a few days to dry as a rule, and the fragrance of pine remains for a long time.

After the sealer has completely dried, I go over the instrument to remove any excess sealer. I can do that with a thin, flexible scraper, or stearated abrasive paper (which does not easily clog up) or by using a rag, wetted with denatured alcohol. (I think the rag with alcohol probably does the best job.)

Then it is time to begin varnishing.

Varnish Beginning

I usually begin with three coats of yellow varnish, to provide a deep “golden glow” to shine from within the subsequent darker coats of varnish:

Color Coats to Come

Next, I will begin to add the colors of varnish I need, to produce the finished look I want. It requires anywhere from eight to twelve coats to achieve that look, usually, but each coat is microscopically thin, so the entire finish is still extremely thin. It will not reduce the sound quality at all, and it will protec the wood from dirt, skin-oil and other substances that might otherwise penetrate the bare wood.

If you would like to immediately see how I finish an instrument, see this link.

I have often had people ask whether I would be willing to leave a violin unvarnished. For the above reasons (plus the fact that I would not put my name in such an instrument:) The answer has always been “No.”

Next time, we will walk through the varnishing process.

A Commissioned 5-String Viola For a Swiss Violist 

Destination: Switzerland!

To begin with, last year, a professional violist in Switzerland contacted me, asking about commissioning a 15-3/4″ 5-string viola. With this in mind, we discussed the project at length.  We ascertained her specific requirements. Obviously, that is her privilege, since she was ordering a commissioned instrument.

Meanwhile, I had undergone surgery on both eyes. As a result, I could not do any detailed work until my eyes healed. The client was very patient: I chose the wood for her instrument, to her approval (European Spruce and Maple,) and ordered the special material for her fittings.

Choosing Materials

Out of concern for endangered tropical woods, the request specified that I use a Swiss product, “Sonowood” for the fingerboard and other fittings. In this  case, the Sonowood is Spruce. They heated it enough to liquefy the internal lignin. Next, they compressed it to three times its natural density. The resulting product is as hard and wear-resistant as ebony. But Sonowood is not endangered: it is Spruce!

Carving The Fittings

On the other hand, Sonowood is expensive and difficult to work with. It was good that I ordered it early.  It took a long time to arrive, and I learned its working properties by carving the fingerboard. Then I made the chinrest, the tailpiece, and the end button. I saved the nut and saddle for last, as I had to fit them to the fingerboard and front plate.

Simultaneously, I also laid out and began carving the neck and scroll.

Once I had completed all the parts, I assembled them and began finishing.

Beginning Varnishing

To “Cut to the Chase,” as people often say, here is how viola looks, today. I have applied the base coats of yellow varnish , and I will soon begin applying the darker layers of varnish.

Finishing Procedure for an Oliver Five String Fiddle

Starting With Bare Wood

Last time, I gave a preview of some of the varnish procedure.

But, to be more specific, let’s walk through the varnishing process:

Peparing for Varnish

First, I removed the fingerboard to give me access to every square milimeter of the outside of the instrument. Next, I used low-angle light, to cast dark shadows so that I could see all the discontinuities, humps and hollows. Then, I gently scraped all the surfaces to remove all of those discontinuities.

Finally, I was ready for the varnish procedure:

Mineral Ground to Close the Pores

To begin with, I used a suspension of fine particles of gypsum in either water or coffee, to form a mineral ground.  First, I brushed the mixture onto all the outside surface except the handle area of the neck, Then, using my fingers, I rubbed the mixture into the wood, so as to fill the natural pores wtih “nano-particles” of the gypsum.

After the mixture dries, the instrument looks chalk-white, and the mineral ground obscures the wood grain.

Then, I used 400-grit sandpaper to very lightly rub off any excess dry gypsum, which still left the violin looking stark-white, as the gypsum had filled the pores of the wood.

Obviously, that (mineral ground) stage of the process looks pretty awful. but the next step (sealer application) always feels like “magic” to me. The sealer makes the mineral ground permanently “disappear!”

Sealer

For the last ten years, or so. I have used a sealer which is simply a thin solution of rosin in alcohol. Sometimes, I use turpentine instead of (or in addition to) the alcohol. Either way, the solvent carries the rosin into the pores, surrounding the particles of gypsum, and thereby rendering the particles tranparent. (However, on this fiddle, I chose to use alcohol as the solvent.)

Obviously, the mineral ground has done its work, plugging the pores against penetration by varnish. However, it has also become permanently invisible.

NOW we Varnish!

When I began making violins, I was using oil varnishes. Later, I switched to spirit varnishes. Today, I am still using a spirit varnish.

The main chemical difference between the two is that an oil varnish is composed of a mixture of a drying oil and a resin of some kind. The varnish-maker cooked the oil and resins together at a high heat, thereby forming a polymer, which is no longer either oil or resin. It does not dry by evaporation so much as by a continuation of the poymerization process, and by “off-gassing” the volatile portions left in the mix.

Varnish makers prepare the spirit varnishes, on the other hand, by dissolving one or more resins in a solvent. Incidentally, the solvent is usually, (but not always) alcohol. When the solvent evarporates, the resin (or resins) remain(s) in and on the wood, to finish hardening. (The mineral ground helps  to prevent deep penetration of the varnish into the wood. This is desireable because the varnish-saturated wood does not vibrate the same in comparison to the unsaturated wood, and it can thereby dampen the sound.)

I always begin with a yellow varnish, so that the yellow base coats will “shine through” any thin areas of the darker vanish, providing a reflective “glow” from within.

Yellow Varnish Base Coats

Here is the fiddle with two coats of yellow varnish:

The grain begins to become more visible with thje addition of the varnish. There is a temptation to stop early, because the grain becomes highly visible after about three or four coats of varnish. But it will look better with more.

Building the Color

I began deepenind the color by simply adding a thin coat of brown varnish, over the yellow base coats.

Deepening the color: one coat brown varnish.

I loved this look…it seemed as though the Quilted Maple wood was in flames, or perhaps as if I was seeing an incredibly dramatic sunset in progress. But I knew it needed more.

Shading

Obviously, (as you can see) I am applying more color in certain areas. I am attempting, thereby, to give the impression of truly aged varnish (where the colored varnish has ben worn away in certain areas through much use.) Some people don’t like that look, but many do. Most importantly, I like it. Charles Beare was famously quoted as having said, “There is absolutely no reason  to ‘antique’ or ‘shade’ a new instrument...unless you actually hope to sell it!” (Apparently I’m in good company!)

So, I apply more varnish in the areas where hands would be least likely to touch, and where the surface is least likely to be abraded by any means. But, I try to be gentle about this, not heavy-handed. Some (few) makers deliberately damage the wood, in an effort to imitate advanced age. Their instruments sell to people who like that look, but I don’t want to do that. Therefore. I simply brush on deeper color in the areas of least wear.

Usually, I prefer instruments to be at least a little leaning toward a red-brown color, so, I needed to add some red.

More Color

I brushed on a thin coat of red-brown varnish all over:

But it still needed more! Consequently, I added more brown in the corners, and allowed it to dry. Then I added more red.

Then, I french-polished the instrument, to flatten any brush-marks. Now I will allow it to dry and harden for a couple of weeks before I set it up for playing. Otherwise, it will acquire deep fingerprints as I work on it.

Another Five String Fiddle in the Works!

I Began this 5-String Fiddle  Sometime Last Year…

Life Happens! Projects get put on hold...

Originally, I laid out the “kits” for six new five-string fiddles, two years ago. However, I had taken on other responsibilities, so I was pretty busy. But I did manage to complete two of the fiddles a year ago. As a result of numerous interruptions, I had barely begun this particular instrument.

We had  lots of interruptions: some good, (a commissioned five-string fiddle) some bad (Health issues for family members.) But, now I’m almost “on the homestretch” to complete my #17 Five-string fiddle.

Where it began

Initially, I bought some very pretty quilted Big Leaf Maple, and some Englemann Spruce, from Bruce Harvie, of Orcas Island Tonewoods. Fortunately, I got the ribs, back and neck out of the same billet of maple. It was nice that the Quilted Maple billet was large enough for that. I cut the top plate and bass bar out of the Englemann Spruce. However, I obtained the willow for the blocks and linings elsewhere.

But then, I laid the instrument aside for a year, partialy completed, while, as I said, other things (commissioned intstruments, family needs, etc,) took precedence.

Eventually, I “drifted back” to complete this instrument in June, and still there were a lot of sidetracks. (“Life is what actually occurs while we are planning something else.“) But this is the final work:

Carving the back plate

First, I completed the carving, of the back plate, inside and out. Then I installed the purfling on the back plate. (I had already completed the front plate, a year ago.)

Carving the Neck

Meanwhile, I began carving the scroll and neck.

The Neck-Set

Carving the neck mortise

First I laid out the mortise with a straightedge and pencil. Then I carved the mortise out, using chisels and scrapers. Afterward, once the neck joint was perfectly fitted, I glued and clamped the neck into the mortise and allowed it to dry.

However, I still needed to finish carving the neck heel and back button, together, as one piece. In that way, all the dimensions and curves will be correct. In addition, I continued to work on the final smoothing and details on the scroll itself.

Finally, I removed the fingerboard. As a result,  I could easily access all of the bare wood for the final varnish preparation and varnishing. (Originally, I had only temporarily attached the fingerboard, by means of three dots of hide glue.)

Varnish Process

In reality, the varnishing process is fairly involved.

First, I apply a mineral ground. Next, I apply a coat of sealer. Then, I begin varnishing. Furthermore, the varnish must be built up, coat by coat. To begin with, I apply two base coats of yellow. Afterward, I work through whatever colors I have chosen to achieve the final result. (Usually, it requires about eight coats of varnish.)

But, here are some pictures taken after the first two coats of yellow varnish:

Getting “Closure!” What goes into the final assembly?

Setting the Neck

I failed to take photos of the actual neck-setting procedure on this violin. (Sorry.)  I will link to a series of photos from a previous instrument.  That one had a major “flesh-wound” mishap. (I accidentally thrust a gouge through my left thumb…but it does include the neck-setting process. And the wound healed!)

This one went very smoothly: I think it took less than an hour to achieve a perfect fit. Then I removed the interior mold, and installed the back linings, so that the corpus was complete and ready to receive the back plate.

Completing the Back Plate

I also had to complete the back plate. I had already completed the outside arching, and most of the interior carving, as well. Still had to finish scraping the interior dead-smooth, then install the purfling, and the label.

Preparing for the Varnish

I removed the fingerboard, to give me easy access to all parts of the front of the fiddle. Notice that the fingerboard had only been held by three “dots” of hide glue. even so, the glue took off a microscopically thin layer of ebony when I removed the fingerboard. (That is what the “black stuff” is.)

Edgework and Varnish Prep

All final shaping has to be completed at this point: any bumps, humps and hollows have to be carefully addressed, using a sharp scraper, before the mineral ground is applied. The mineral ground is a suspension of extremely fine particles that “plug” the pores in the wood, so that the varnish does not penetrate deeply and deaden the sound.

I apply it wet, with a brush, and vigorously rub it into the wood with my bare fingers, then rub off as much of the excess material left on the surface as I can. It is not supposed to be “on” the surface, so much as “in” the surface of the wood.

The wet mineral ground temporarily darkens the wood, but, as it dries, it turns stark white.

The next step is always pretty amazing: when I brush on the sealer, it surrounds all the “white” particles in the wood, and they become transparent. Look at the “before and after” photos of the back plate, as the sealer is applied:

From this point forward, it is just a matter of applying numerous coats of varnish, and adjusting the color as the process progresses. Furthermore, I want all the parts to “fit together” in terms of color. (You can see that there is a difference between the front and back color, for example.)

Next time, we will talk about color varnish coats.

Progress Report on a Custom 5-String Fiddle

My Neck and Scroll process

Originally, when I first began making instruments, I laid out the scrolls with a pencil and simply started carving. However, that was extremely labor intensive and not very accurate, either. As a result, it was very easy for me to lose track of where I was going, and ruin a scroll by carving away wood I really needed. (Obviously, that is a “bitter pill to swallow,” having to scrap a scroll and start over.)

Learning from a Better Maker

So, then, what has changed? Fortunately, I watched how a viola maker in Brazil (Luis Manfio, of Sao Paulo) carves his scrolls, on a photo-essay he once posted. To begin with, he used a fine-toothed saw to cut “tangents” to the scroll pattern. Then, he used the same saw to follow the side surfaces of the scroll and remove the scrap wood. Understandably, this was a much better way than I had been attempting, so, ever since then, I have followed that path.

So, then: here is what that process looks like, using the current commissioned instrument as an example:

This is how the final tangents look. (Notice, too, an “error” pilot hole. It will be plugged befor the real peg holes are drilled.)

Then I carefully cut away the waste wood from the center area of the scroll, using small gouges.

Installing the Fingerboard

After the scroll is close enough to correct that it will not be changing much, I will trim off the excess wood from the sides of the “handle-portion” of the neck. Then, I will temporarily install the fingerboard, using three “dots” of hot hide glue.

New Commissioned Five String Fiddle On the Way!

New Commission!

Unusual  Woods

A customer ordered a new, custom-made Five String Fiddle, and it is on the way!  He chose heavily spalted, heavily-flamed, Oregon Big Leaf Maple for the back plate, the sides, the neck and scroll. My wife’s parents gave me the wood from this maple tree.

Ann used to play under and climb on this tree as a child, and we hated to see the tree cut down. Her parents still live there, less than four miles from our house. However, they had to remove the tree because it was dying. I have salvaged wood for a few instruments from that tree and they all look and sound wonderful!

Given a choice between Spruce and Douglas Fir, the customer chose the Douglas Fir, for his front plate. This tree also grew just a few miles from my home. (A famous violin and viola maker, Otto Erdescz  (1917-2000) used to make violins and violas with Douglas Fir soundboards. Professional musicians still play some of them, today. But very few luthiers use Douglas Fir. I didn’t either, until a few years ago!)

Not my usuaI Choice in times past

For many years, I refused to try such a thing. But a friend gave me a load of very straight grained Douglas Fir firewood, a few years ago.   I was splitting some of the firewood,  and the split-off piece hit the ground: it rang like a bell! I had never seen such straight-grained, clear Douglas Fir, with zero runout!

Unfortunately, that particular piece was too short for a fiddle. I had to search through the pile for a piece that was long enouigh for a violin plate.

Since then, I have made several such instruments, and they all sound great. (I find that the Spruce is definitely easier to work with, though, and, for classical, orchestral instruments, I still use only European maple and spruce.)

Customer Preferences:

This man showed up at my shop and he played all the five string instruments I had. (He really had not played 5-string instruments before. He laughed for joy, hearing the rich deep C-string on each one.  After a short while, he declared, “OK, I’m addicted!”)

He played the full range of all of them. He finally settled on my earliest unsold 5-string (#3 on the “Chronology” page) as being exactly what he wanted.

But not to buy that instrument. No! He wanted a commissioned instrument “just like that one!” (He wanted one especially built for him! Sure! We can do that!)

And, as it turned out, that was a good thing.  A week later, the next customer who came to try out all my instruments  also loved that fiddle, but she bought it that day, and drove away! So, it is gone, now!

Which Mold?

I knew which of my molds was the source of that fiddle: I have made at least four off of that specific mold. All of them have sold, now, so, for the moment, there are none available. (This instrument will “solve that problem,” for a moment, but it will disappear immediately after completion.)

The commissioning customer also wanted local wood. so that he could say, “My violin came from a tree on that hill!” So…choosing the wood was the first step.

Choosing the Wood

The model I would use had already been chosen, so that was not an issue. I also knew what the wood source would be: I still have a little of the maple my wife’s parents had given me. And, with the customer’s approval, I chose a clear piece of Douglas Fir, salvaged from the firtewood I mentioned earlier. He loved both pieces.

Here is a closer picture of the maple:

I book-matched the spruce, by cutting a single billet in two equal halves and gluing them together to make the front plate.

I laid out the neck outline on the billet I had chosen for the neck, and I drilled the pilot holes for the tuning pegs. Then I cut out the side profile on a bandsaw.

Mold Preparation

Meanwhile, I got the blocks glued into the mold. Then I  traced their shapes from my template, so the whole job could begin. I also  planed away the rough surfaces of the maple to ascertain that it actually would serve well as the back plate of a new five-string fiddle. And, I found that it was just a little too narrow in the lower bouts.

So, I “transplanted” a small piece of wood from the area above the upper bout on each side and grafted them in on the lower bouts. (This practice is not at all uncommon: It will be every bit as strong as the center seams on two-piece backs. And, once the double purfling is installed, the joints will be nearly invisible, under the varnish.)

Preparing the Ribs

I had chosen wood for the ribs, as well, and I sawed them to a thickness of a little over 2 mm. I thinned them, using a wooden fixture I made, clamped to my oscillating spindle-sander. The fixture allows me to  gradually reduce the thickness to 1 mm.

Here are the ribs:

Installing the Ribs

Next, I cut the ribs to the correct length and width. I carefully considered which grain from one side would “mirror” which grain on the other side. I had already been tinkering on the neck, as you can see in this photo, but I will explain that process later.  (It isn’t always possible to do everything in a precise order. While I am waiting for  glue to dry on one section, for example, I may jump ahead on another piece.) You can see the bookmatched front plate, too.

I cut all six ribs, and marked them as to inside, outside, upper and lower ends, etc, as well as which side of the fiddle they would call their home…treble or bass side.

Then I bent the ribs using a hot “bending iron” (actually made of aluminum, but, in the old days, they were iron.)

(I forgot to take photos of the shaped blocks: Sorry.)

I had cut and shaped the corner and end blocks, already, so I applied a generous coat of hot hide glue to one block at a time. then, I clamped the rib into the block surfaces, making certain that everything fit correctly before tightening the clamps.

First, I installed the center bout ribs, and when the glue had dried, I used the spindle-sander to trim the ends of those ribs to match the curvature of the outer faces of the corner block, so I could install the upper and lower ribs. Here are the upper ribs, glued and clamped:

Center and Upper bout ribs installed, using hot hide glue and clamps.

The lower end of the bass-side center bout rib was not fully tight, so I reglued it and reclamped it. (left lower side of photo.)

Then, when that glue was dry, I installed the lower ribs, by turning the mold upside down in the vise, so I could see clearly. It also meant that both hands were free to adjust the rib position, and apply clamps.

Tracing the plates

Once the linings were installed and the ribs thus strengthened, I could trace the shape of the plates, and begin cutting things out.

Need More Fiddles! Beginning Six New Five String Fiddles!

I Failed to “Keep Up!”

I shipped the last three fiddles I had made, so the “cupboard” is looking pretty bare!

Unfortunately, I spent a lot of time messing around, this year, trying to build a travel case for the Travel Bass I built last summer. (I really need to complete it. The bass isn’t going anywhere without the case.) Also, the last two fiddles I had made were literally hanging around the house, and so, I wasn’t feeling pressed to build more of them right away. I found it to be a busy year in a lot of other ways, too.

Sudden Changes

Two customers came, and rather abruptly, those two most recent fiddles  suddenly found homes.  I only have two five-string violin-size fiddles left, both of which I had made several years ago, and they both play very well. However, the ones I am building currently are my best work, and that is what I want to put in players’ hands.

The Plan

Therefore, I decided I had better “hit the Lutherie trail” in a big way. First, I selected six of my molds (five in the photo, below: the sixth shows up later.) Then, I glued the blocks in place, to begin a group of six new fiddles. Next, I plan to select and prepare materials, and match them together into “kits.” In this way, I know which top plate goes with which back plate. neck, and ribs, etc.

Afterward, I plan to begin building them in pairs, but I will always have another pair ready to begin, if things slow down at all.

The Process:

Look closely, and you soon will see the transparent plexiglass template in the photographs above and below. Because the template is clear, it is hard to see, but it gives the precise shape I want for the outline of my blocks. I use a ballpoint pen to trace the shape onto the blocks.

I use the template to trace the exact shape I want for my blocks.

 

Next, I use a saw to roughly cut out the shapes. Afterward, I use an oscillating spindle sander to shape them more precisely. Using an old candle, I rub parrafin wax on all the exposed edges of the molds, so that an accidental drop of glue can’t bond them to a rib. Initially, I glue the ribs only to the blocks and linings. Ultimately, I will remove the mold, before closing the body of the instrument.

Here are the blocks, shaped and ready for ribs.

Wood Choices

Then, I cut the ribs from wood that match the back and neck, as closely as possible. Usually, I try to get them all out of the same billet of wood. Over the years,  I have harvested some of my wood, myself. However, A friend (the late Terry Howell) gave me a great deal of curly maple, in log form. Immediately, I had someone mill it up for me on a large portable bandsaw mill.  In other cases, I have simply bought wood from tonewood dealers.

I have used a variety of woods for the back plates. These (below) are all Big Leaf Maple. But, I have used a wide variety of other woods.  When I build classical orchestral instruments, I use only European Maple and Spruce.

I bought the wood (in the pictures below) from Bruce Harvie, of Orcas Island Tonewood Company. That piece of Big leaf maple on the right measures 2″ thick, about 6″ wide, and 16″ long, or more. The large billet allowed me to cut the ribs, neck and two-piece back all from the same billet. I cut up the Englemann Spruce billet on the left. to provide two tops and nine bass-bars.

Processing the materials:

To begin with, I used a bandsaw to slice off the rib material. Then, I laid out the actual shape I needed for the back and neck. (I did not make the traced “shape” visible in the above photo. That is just the way tonewood dealers “spark the imagination” of their customers.)

I sliced the back plate shape in half lengthwise, originally. Next I planed the two edges perfectly smooth and flat. Finally, I glued the halves together, to form the back plate.

While the glue was drying on the plates, I traced out all the neck billets. I used a bandsaw to cut them out, to produce “neck blanks.”

Looks like a “bouquet of fiddle necks.” They will be matched with their respective backs and ribs.

 

In addition to the preparation of the heavier components, I used a bandsaw to slice rib material from appropriate wood to match the wood of the backs. For example, a darker maple back required darker maple ribs. I then sanded them to 1 mm final thickness, using the oscillating spindle sander.

Ribs for 5-string fiddle.
I was glad I had rib material that matched the color of the old wood for this fiddle. That back (below) was harvested in September, 1983.

After thinning the ribs, I used a knife to cut the ribs to size.

Each set of ribs requires three pairs, in lengths for upper, center and lower bouts.

Douglas Fir

Usually, I make the top plates of my instruments from some type of spruce. (Sitka, Englemann, European or other species all work well.) But, sometimes (rarely) I use other woods: this one is Douglas Fir.

Otto Erdesz used Douglas fir for the front plates on many instruments. I have seen and played one of the violas he made of Douglas Fir. When I found some Douglas Fir with great tone qualities and very straight grain, I decided to try it, emulating his success. Thus far, I have only used Douglas Fir once, but it turned out to be an excellent fiddle, so, I am doing it again.

And, finally, I see the “kits” beginning to emerge!

These Kits will help me keep focused and encouraged about building the six new fiddles.

 

I will try to provide updates and to post progress reports.

Varnishing a New Handmade 5-string Fiddle

5-string Varnish progress

Sealer

Last post included the sealer, which, to be honest, looks awfully nice. But it isn’t varnish: it was just a resin dissolved in turpentine. The sealer is used to lock in the mineral ground and seal the pores against excessive varnish saturation (which could dampen the tone.) It looked like this:

So, from that point forward, the varnishing began:

Early Varnish

The first coats of varnish I use are pretty intensely yellow. I want that golden glow to shine through the other colors, wherever there is any wear, or deliberately thin spots in the color coats. After the yellow varnish I begin selectively darkening certain areas, corners, etc..The purpose of the selective shading is to enhance the overall look and feel, visually.

So, here are the front and back after the early coats of varnish. Pretty much all of this is from the first day or two of varnishing:

Later Varnish

After the early varnish is well-cured, I scrape or sand away any sags, drips, or brush-marks. I also remove any brush-hairs that might have been overlooked earlier. Then, I lightly sand over the entire instrument. The aim is to produce a smooth surface upon which to deposit subsequent coats of varnish. (Usually, there will be about eight coats, overall, by the time I am done varnishing.)

I add the deeper color coats, still striving to produce the shading that would go along with the old instruments that everyone finds so attractive. (I have numerous excellent photos of “old-master” instruments to study, from which to gain ideas as to what is “normal” wear.) So, here are photos of the front and back of the same instrument after further layers of varnish have been applied.

Back view with later varnish layers. I like that back, of Oregon Big Leaf Maple!

 

Future plans:

I anticipate about two or three more coats of amber varnish to deepen the shine and improve the clarity. There will be some re-touching done as needed, of course. This will be especially true after I re-install the fingerboard and fit the pegs, to begin set-up. But, the varnish is looking pretty much the way it will when it is finished, in terms of overall color. The red will probably look a little less intense, but it will still be there.

I hope to have it playing next week sometime.

This is the “sister instrument” to a five-string fiddle made last year. Each was built from wood salvaged from the scraps after I built a five-string Double Bass last Summer.

Here are some clips of the sister instrument played by Andy Pastor: https://fivestringfiddles.com/2020/12/21/first-complaint/
