More 5-string Fiddle Progress

Five-String Fiddle Progress

(Further progress on building a custom-made 5-string bluegrass fiddle.)

Neck Set

The neck was ready to set into the neck-block, late last night, but I had reached my physical limit. So, today, I prepared both the neck and the garland, by ascertaining that all angles and dimensions were correct, and then laying out the shape of the neck mortise on the neck block of the garland.  This is a critical step in violin-making and always raises my blood pressure a little, as I know that, if I make a mistake, it will require serious rework to get back to a usable status.

However, this time, the job went pretty smoothly, and I was able to set the neck in a fairly short time. One thing I do a little differently than I was originally taught, is that I set the neck before installing the maple back plate. This allows me to achieve a good fit with the rib garland and neck block, and not have to worry about the fit against the back plate button. Then I saw off the stub of the neck heel, and plane and file it flush with the rib garland. After I remove the mold and add the back linings, I will level the back of the garland, and be ready to trace the back plate shape.

Here is the completed corpus (Sitka Spruce top plate and Big Leaf maple ribs still on the mold) with the wild-grain Big-leaf maple back plate billet.

Mold Removal

So, the next step was to remove the plywood mold. This is another stressful step because it involves literally using a hammer and chisel, to break the glue-bond between the blocks and the mold, so as to release the garland from the mold.  I used to have a difficult time doing this, because occasionally a drop of hide glue had seeped between the rib and the mold, and anchored the fragile rib material to the very solid mold. The likelihood of breaking a rib at that point became nearly 100%. Eventually, however, I learned to liberally coat all the non-gluing surfaces of the mold with candle-wax (paraffin,) by vigorously rubbing a candle over all the areas I felt were likely to get a drop of glue on them.

The result today was that, when I removed the mold, it went smoothly, and I could see a place where glue had definitely intruded but it had dried with zero adhesion to the waxy mold. (What a relief!)

Installing the Back Linings

The linings are important for two reasons: they strengthen the fragile rib-edges, and they triple the gluing surfaces between the rib-garland and the front and back plates.

So, I cut the mortices in both sides of each of the six blocks to receive the lining strips, and then inserted the linings dry, to get a perfect fit.

Afterward, I removed each lining, one by one, coated them liberally with hot hide-glue, and re-inserted them, clamping immediately with small spring-clamps.

Shaping Blocks and Linings

If you look closely you can also see, in the above photos, that I had trimmed the blocks on the front side, before removing the mold. After the glue is dry on the back linings, I will also trim the back side of the blocks, to achieve a smooth, curved surface on the interior of all the blocks. At that same time, I will taper the linings so that they are very thin on the edge toward the middle of each rib, but still 2 mm thick at the edge where they will contact the back and front plates.

After that, it will be time to level the back surface of the entire corpus (garland and neck-heel) so as to fit tightly against the back plate billet. Then I can trace the final shape of the back plate, cut it to shape, and get going on completing the back plate.

For now, I am satisfied to allow the glue to dry, and take the rest of the evening off.

Commissioned Handmade Five-string Fiddle Beginning

Starting a new 5-String Fiddle

The Materials:

A few weeks ago I announced that a new fiddle would be beginning. Now I have a few photos to show:

The top plate is Sitka Spruce, from Bruce Harvie. The customer wanted “Oregon wood,” and the Big Leaf Maple is definitely from in my neighborhood, here in Oregon (I helped harvest it;) but the Sitka is just a species that grows here…I don’t know where it was harvested.

Beginning the work of building a 5-string fiddle:

I book-matched the spruce, to form the basis for the front plate: a solid plate with a tight glue-line down the center.

I used the mold (or form, as many people prefer to call it) that matched the fiddle the customer liked best. Then I added willow blocks to become the corners and end-blocks, and I traced the intended shape of the blocks from the mold template onto the back-side of the blocks, where they are flush with the mold.

Added the ribs, of the spalted maple the customer liked, and glued them to the willow blocks. Afterward, I added linings, also of willow, and let them into the blocks and glued them to the ribs and the blocks.

Then I traced the shape of the garland onto the top plate material, using a small washer as a spacer, and a ball-point pen as a scribe. I completed the corners using a straightedge and a series of circle templates. Finally, I marked the edge at exactly 4 mm thick, and carved the arching, using gouges and planes and scrapers.

Then I marked the layout of the double purfling and the f-holes, and began incising them into the Sitka Spruce.

Sometime in the midst of all the above work, I laid out and began carving the scroll and pegbox. That wild grain is very tricky to carve, as it changes direction constantly.

I went ahead and completed the purfling and the f-holes, so that I could prepare the plate to be glued to the garland.

I also added the bass-bar, chalk-fitting it to perfection, and gluing it in place, with hot hide glue. The bass-bar will be carved, planed and scraped to the proper shape after the glue dries.

The fingerboard is Ipé, as requested by the customer. It is an extremely dense hardwood, but not threatened as Ebony is beginning to be. It finishes to a dark brown and looks good, as well as wearing well. It is extremely difficult to work, though, so it may take time to become popular with makers. The saddle and the nut will also be Ipé, but the pegs will be ebony, simply because I have never mastered the lathe-turning of tuning pegs.

And that is pretty much where things stand, for now. I will try to post pictures as they become available.

New 5-string Commission on the Way!

New Five-String Fiddle Request!

A client contacted me through this website and asked whether I could build a 5-string fiddle of primarily Oregon woods. (Sure!)

Test-Drive of existing fiddles

We made an appointment and she came for a visit. She played eight of my hand-made instruments (all good fiddles), finally declaring a particular one to be exactly what she wanted, except that she did not care for the look of the one-piece Sitka Spruce top plate. It had very wide grain on the bass side and narrower on the treble side. (It sounds great, but the looks were bothering her.) Soooo…

Custom-made Five-string!

I went into my storage and retrieved a really wild-grained piece of Big Leaf Maple, and two billets of very straight, even-grained Spruce: one of Englemann, and another of Sitka: she chose the Englemann and loved the maple. She wanted an instrument essentially the same as that first one, but without the odd-looking belly grain. (The same model; made on the same mold (form), and sounding just like it, as well.) It will be tough to do, because the one she really likes is already five years old; it has had time to settle, be re-adjusted, and settle again. (Yes, it sounds good!)

Select Woods and a Good Start

So, we went out to one of my other buildings and hand-picked some likely-looking wood for the neck and ribs, and we were ready to do business. She presented a deposit, and I suggested that she take home the one she loved, for the time being, to keep her interest up while waiting for me to complete her personal treasure. She went home happy, and I began sorting willow for blocks, finding my proper templates, and enjoying the prospect of a new five-string fiddle build. I will post follow-ups as they occur.

Thanks for looking.

I will post this over on the Bluefiddles page, as well.

Violoncello Piccolo Project

Piccolo Cello Essentially Complete

Remembering it is a “Mock-up”

This is not a cello I have built from raw wood. It was an inexpensive, small Romanian Cello I salvaged years ago (I had forgotten that it was Romanian… I thought it was Chinese) and for which I had never found a buyer. Currently, there is someone interested in a handmade five-string cello, and leaning toward the piccolo model, as that is the traditional size from the time of J.S. Bach. But there is no standard size of which I am aware, so I removed the neck of the little old cheap cello and made a 5-string neck and scroll with which to replace the old neck.

Here is the result:

 

Piccolo Front

Piccolo Bass Side

Piccolo Back

Back of Scroll

It plays fairly well, for what it is. I have a difficult time becoming accustomed to the sound of the High E string in a cello, but I can see the value for certain applications, as it would effectively eliminate “thumb-position” in a lot of pieces.

If a person wanted a full-size five-string cello, or a 3/4- size, a 7/8-size, or what have you, I can make those, too.

I see that Helicore is now providing a five-string set for a full-size cello, so I may have to try one, just to see how the new strings sound.  🙂

Five String Cello Progress

Five String Cello Project in Progress

Upgrade to my brain (memory) needed, it turns out:

It turns out that the “Hybrid” cello I chose for the donor corpus, was actually solid wood on back and sides, as well as the top. So, that’s a good thing!  It is still a rather cheap instrument, and so, this is still just a “mock-up” for R&D, so to speak. I will begin the “real thing,” (all handmade by me,) when the customer is satisfied that this is what he wants. (One thing he wanted is all Oregon woods, as far as possible. So this doesn’t qualify.)

Five-string neck is on the way:

The scroll is nearly complete, and I decided to go with the carved back on the scroll, as some of the early instruments had, just for fun.

Pressing onward! Hands are getting tired!

 

There will still be a lot of scraping and polishing to do before it is done. Also, I have to make a fingerboard to fit the neck; but then I can install the neck.

Pushing forward to the finish!

Lots of Delays and New Project

Lots of Delays and New Project

Delays:

Home repairs and equipment repairs.

We had a few break-downs this summer. The lawn tractor, a faithful beast of thirty years, suddenly quit working. Turned out to be a bad PTO clutch. I was eventually able to order new parts online, and do the work myself, but it was a discouraging project, as I am really not a mechanic, by inclination. But it works again.

Meanwhile, it also turned out that one of our toilets had been leaking under the floor, and had ruined the floor, so the whole underlayment had to come out. I replaced it with something called “wonderboard”…a concrete product, reinforced with fiberglass… nasty stuff to work with, but relatively impervious, so I was glad to go ahead with it.  mudded all the screws so they were flush, and all the seams, etc., then sanded the whole mess flat. Then linoleum, and sealer, and wallpaper. Finally got everything back in place, working, no leaking pipes, etc.,  just Wednesday of this week. Glad to be done with that.

New Project:

5-String Violoncello Piccolo

A fellow called me a while back, having seen my 5-string fiddles, and asking for a custom-made five-string cello, using all Oregon woods, if possible. (No problem…but most of the historic 5-string cellos I am aware of were piccolos…considerably smaller instruments, and quite rare. Only a few surviving models.) Nope, he wanted a full-size. Okeedoke, no problem. They even sell Cello-string sets for full-size 5-string cellos.

But he thought it over, and now is leaning toward a piccolo, just because. (They really are a special instrument!) But, now I do have a problem: I don’t have one to show him.

So, since I am short on time, I am making an experimental mock-up of the correct size, using a fractional-size hybrid cello (laminated sides and back; carved top), and replacing the normal neck with a neck and scroll specifically designed for a five-string instrument. It will not be the quality instrument he will expect in a custom-made cello, but it will give him the opportunity to experiment with the smaller size and the five strings.

I had plenty of maple on hand, but not thick enough for the neck, so I laminated two 1-1/2″ slabs, side by side, to make a thick billet, and then sawed out the blank.

I laid out the details of the scroll and neck; then used a saw to begin removing excess material. It is hot and humid, today, and I tired pretty rapidly, so I only got partway done:

Starting to smooth up a bit, but there is still a long way to go.

Plan:

I hope to have the scroll and neck complete in a day or two. I then intend to make a fingerboard and nut of Ipe, a non-threatened hardwood, and install the assembly on the hybrid corpus, immediately thereafter.

At that point, it should be down to the final finish of the neck and fingerboard, and set-up of the instrument in its new life as a  five-string cello piccolo. The corpus is already in good shape, so it should not require additional attention.

I will post photos, as they become relevant.

Five String Fiddles in the White

“Shop-made” 5-strings

Not my preference, but…

There are folks who want a five-string fiddle, and who can’t justify the expense of a hand-made instrument, made by an American luthier. I completely understand that, so I am going to try an experiment of sorts: I bought two instruments in the white …unvarnished, incomplete, etc.  One is a five-string violin (standard size), with a one-piece back, and the other is a 15″  5-string viola.

five string fiddles in the White
A 5-string violin and a 15″ 5-string viola.

The viola looks much larger than the violin in this photo, but, in reality, the body is 1-1/16″ longer than that of the violin, with a proportionately larger neck and scroll.

Possible Glitches

I can see some potential problems, and I will see whether I can correct them before completing the instruments. There are certain details necessary to a good instrument that have been overlooked in these two. Specifically, it is needful to arrange the locations of the pegs in such a way that the higher strings do not rub on the pegs that are lower in the box. Both of these instruments fail that test pretty badly, but other than that, they seem to be very well-made, if possibly a little heavy.

Up until now, I have only bought standard, four-string instruments-in-the-white, and they have all turned out quite well. I hope I can make these two turn out to be great instruments, too, but… as I said, this is an experiment, of sorts.

At any rate, I will go over them carefully to try and bring them up to my standards as far as those things go. The workmanship is very good, though: I hope they sound great. I guess we will have to wait and see.

Shop Instruments, as a Principle

The advantage of using an imported, unfinished instrument like this, is that it drastically reduces my labor investment, and I can pass the savings on to customers who want a good instrument, but may not want to spend so much.

I label my shop instruments as “Atelier Chez les Eveques“, (the Shop at the Bishops’ Place.) Unlike my handmade personal instruments, they are not signed or numbered. But they are good instruments, and all who have bought them have been well-satisfied.

I will show progress on these two instruments as time permits. (We have had a host of home-repairs to worry us, lately….)

Thanks for looking.

June 22nd Progress Report

Some Progress is better than none!

It has been a frustrating series of weeks: all the usual responsibilities, house guests, etc., plus a few unexpected items. The lawn tractor suddenly quit mowing, though it ran fine. We narrowed it down to being a bad PTO clutch, so that is just another thing to take apart and replace.  Guess that’s what happens when you use 30-year-old equipment. 🙂

Then, two days ago, my beloved better half, Ann, discovered that the side porch steps are in advanced stages of rot…so, today, we went and bought all the pressure-treated lumber to replace them. They, too, have been in place for over 30 years, so, I guess, they have served well.

Progress on the 5-String Fiddles

I did manage to make a little progress on some of the acoustic five-string fiddles I had begun, however:

  • All the linings are in place for two of the instruments (violin and the 14-7/8″ viola.)
  • The front and back plates are traced and cut out for both of those instruments.
  • The front plate graduations are complete for the 14″ viola, and
  • The f-holes are cut out on the 14″ viola, but not refined.

So, this is where things stand, at the moment:

Here is the “Strobelesque” garland with its front and back plates:

Rib Garland and rough-cut plates for the “Strobelesque” fiddle.

No carving at all has been done on the plates, and the Sitka Spruce front plate is still nearly an inch thick. I will plane it down before I begin arching, of course. I do like the look of the spalted maple back and ribs. This maple was from an old Big Leaf Maple tree on the property where Ann grew up. It had begun to show signs of decay, and was removed for safety’s sake. Too bad for the loss of the tree, but it is nice wood.

Here is the 14-7/8″ Viola garland with its front and back plates.

This one is my own design. In fact, it was the very first form I ever made, thinking I was just going to make a viola for my youngest son (whose name is on the form, along with the date: 1999.) As it happened, I discovered that lutherie is addictive, and I have been building instruments ever since. 🙂

The center-lines on both plates are ink, not a glue-line: this instrument boasts both a one-piece Spalted (Big-Leaf) Maple back plate (also from the tree at Ann’s childhood home) and a one-piece Sitka Spruce front plate.

Here is the progress on the 14″ Viola:

garland and plates
Rib garland and nearly completed plates for a 14″ five-string viola.

This one is my own design, too: it is the same length as a standard violin, but much wider in the lower bouts, and deeper in the ribs. It will be interesting to see how it works as a five-string fiddle. (This is a first.) This one has an Englemann Spruce front plate and a one-piece Big Leaf Maple back from a log I was given by Terry Howell, years ago.

 

I will post more reports as the work takes place. Feel free to contact me if you have questions.

5-String Fiddle Linings

Why Linings in a 5-string Fiddle?

What is the use of linings?

In most of the members of the violin family, including the five-string variants) there are narrow strips of wood glued to the inside of the ribs, all around the edges, called linings. On some double basses the linings are actually on the outside of the ribs,  as well as the inside, following the edge of each rib. The purpose is the same in either case: it is to strengthen the very fragile rib material as well as tripling or quadrupling the thickness of the gluing surface at the edge of the rib. This is so that the rib garland can be securely attached to the front and back plates, also making it possible to remove those plates without breaking the ribs, when repairs are needed.

Wood for linings

I like to use willow for my linings when it is available, because it is easy to bend and fit to the ribs, as well as being very easy to carve, when it is time to taper those linings, and make them fair into the inside surface of the rib structure. Many makers use spruce, and I have done so as well, but have decided that I prefer willow. In fact, when I can get it, I specifically prefer Weeping Willow above anything else I have tried.

Installing linings

So…I arrived home fairly tired this evening, but I fired up the glue-pot, and prepared to install some linings: You can see the center bouts on the right-hand instrument’s ribs are already in place, making the edge 3 mm thick, instead of barely 1 mm.

When I pre-form the linings, I begin by using my bandsaw to cut a “plank” of willow, 3 mm thick, then thinning it to a very consistent 2 mm thickness. I use a “wheel-style” marking gauge, set to 7 mm width, to deeply score the “plank” along one edge, then flip it over and score the opposing face, effectively cutting the rib free from the “plank.”  Then all I have to do is bend those linings blanks around my bending iron, and produce a pile of “ready-to-use” linings for my violin ribs (see below.)

linings in five-string viola and 5-string fiddle
Rib linings in the 14-7/8″ 5-string viola and one of the 5-string violins. In the foreground you can see the linings I have pre-formed to approximately the required curvature .

I use a small sharp knife and a tiny gouge to make a small mortise in the junction between blocks and ribs (12 places on each face of the garland.) I only use hot hide glue on instruments, but the hot hide glue cools and gels rather quickly, so I cut the pre-formed linings to the proper length, and fit all of them into the garland, dry.  One by one, I then remove each lining, coat it liberally with hot hide glue, and quickly re-insert it into the tight-fitting place prepared for it.  I pinch hard, with my left forefinger and thumb, to squeeze the joint tight, and then use my right hand to apply a spring clamp. I move over a half-inch, and repeat, until the whole lining is tightly secured with glue and clamps. The little spring-clamps will hold the freshly glued linings in place until the glue hardens.

The same principle works for larger instruments, but the ribs are bigger, and I use bigger clamps.

Anyway, that is all I accomplished this evening. Possibly tomorrow I will get the rest of the linings into the other instruments.

Once the linings are in place, the ribs are a good deal less fragile, and less prone to breakage. That is a relief, as they are really easy to break, without the linings.

Follow along and see the whole build!

Four Five-String Fiddles

Five-String Fiddles Progress Report

The last time I presented anything about these instruments, I think it was on another site, so– here is how they looked at that time (earlier this week, perhaps.)

Blocks and C-bout ribs installed. Blocks installed, and necks cut out.

 

In the above photo, all you can see is three violin forms, with blocks installed, and some of the wood that will go into each, including the necks. I already had a fourth instrument (a small viola) begun, which was not in the picture.

So, here is that 14″ 5-string viola, well on the way to completion, but still with a long way to go…as of today.

14″ viola 5-string in progress.

 

And, as promised, here is a progress report on the other three:

5-string 14-7/8
5-string 14-7/8″ viola in progress.

On this instrument, the ribs are installed, but no linings as yet, and, while the Maple and Spruce have been selected for the front and back plates, they are essentially untouched. The neck has been traced out and the outline cut, but it, too, has far to go.

 

Guarneri-form 5-string fiddle
Guarneri-form 5-string fiddle in progress.

For this instrument, a five-string fiddle being built on the form of the 1735 “Plowden” Guarneri del Gesu, I had a top plate left from a previous project on the same form, so I opted to use it, with the spalted Big Leaf Maple back and ribs. No linings, yet, but they have been bent and are ready to install. The neck is from a different Big Leaf Maple, which came from the yard of the property where my wife grew up.

 

5-string fiddle
5-string fiddle on “Strobelesque” form, in progress.

 

Henry (Senior) would not have recognized this form, but it was loosely derived from the form in Henry Strobel’s book, “Violin-making, Step-by-Step”…so it is called “Strobelesque.” In this photo, the glue was not dry on the treble-side upper rib, but I didn’t want to wait, so I took the photo with the clamps still in place. Again, no linings, yet, but they are bent and ready to install. Here, too, I had a partially completed top plate, and elected to use it. The back and sides are heavily spalted Big Leaf Maple, and the neck is also Big Leaf Maple, though from a different tree…the one in my Father-in-Law’s yard. A few years ago, they decided that tree had enough rot to be dangerous, so they took it out, but it provided wood for a number of instruments.

My son Brian Bishop builds high-quality guitars, and managed to salvage several guitar sets beside the various violin and viola sets I saved. I got one cello set out of it, too…it will become a cello for my beloved wife.
