Five String Fiddle Progress

A fellow approached me a few months back, asking whether I could build a five-string fiddle of some exotic wood which he had bought almost 33 years ago, and which he had hung onto all this time. Of course I am delighted to make an instrument that is special to a client, so I said “Sure!”

Wood

Here is the wood (Nice stuff! I can see why he hung onto it!):

The neck, back and ribs will all be cut from this block. Actually there will be a fair amount left over, so I will try to use it in an efficient manner so that he can use the scraps for something nice, too. The front plate will be spruce. The blocks and linings are willow…not sure which specific variety.

Templates–Patterns

Here is how the pattern will fit–with lots of room left over:

Plenty of extra from which to cut rib-stock.

The section from which the back plate will be cut will be sawn into two pieces, each half the thickness of the original block. The two pieces will be glued edge to edge, so that they are “bookmatched”: that is to say that the straight edge of the mold template will become the centerline of the back plate. (I will show photos of how it is done when I get to that part.) The same thing will happen with the spruce for the front plate.

Progress and Plans

The five string fiddle will be built to my usual “Oliver 5-string” Pattern. So, the first thing I needed to do was to cut the ribstock using a band-saw. (I sliced them off at 2mm thick, later to be thinned to 1mm thick before bending to shape.) I also cut willow blocks for the four corners and the two ends.

Then I needed to glue the blocks into the mold, and mark them for their outer shape. This shape will be the inside shape of the ribs, and the blocks will become a permanent portion of the finished instrument. The mold will be removed as soon as the rib structure is safely glued to the front plate (not pictured here.) Once the glue was dry, I laid the mold-template on the centerline of the blocks, and scribed around it with a pencil.

After the blocks were marked, I was ready to begin shaping them. I really only want the center curves shaped to their final profile: the rest of the corner blocks need to stay a little thick, so as to guarantee they will not deform when I am gluing and clamping the center ribs in place. I went ahead and shaped the end blocks as well, as that does not hurt anything.

Here’s a side view of the same thing:

Once the center ribs are bent to the correct shape, I will glue them to the center bout surfaces of the corner blocks, and after the glue is dry, I will shape the outer surfaces to receive the upper and lower ribs. From that point forward, it will begin to look more and more like a violin.

I will keep you posted.

Neck and Scroll Carving Procedure

Please share with your friends!

Two Hand-carved Five String Fiddle Scrolls in Progress

First: Lay out the Side Profile

I created a template for a five-string fiddle neck and scroll when I made my first 5 string blue-grass fiddle. The template is fairly crude; just a cutout of thin plywood (door-skin material). I have other templates I have made of aluminum, and still others of plexiglass plastic. But that is the starting place, regardless of template materials. I know how thick the billet needs to be, and how long, so I simply place the template on the billet of curly maple, and trace around it with a ball-point pen. (I used to use a pencil, but the ink is easier to see against the wood.)

 Next: Cut out the Profile

I use a band-saw to cut out the profile of plates and necks. I do have a bow-saw that I made for such work, and I can use it if need be. but I find the bandsaw so much easier to control and so much faster, and the results are so much better, that I quit using the bow-saw after about two instruments. It looks nice, hanging on the wall.

Power Tools vs. Hand Tools?

Some people are insistent that the “only right way” to make a hand-made instrument is to use nothing but hand-powered tools. I have built one instrument using only hand tools. I will probably never do so again. There is a reason that bandsaws, drill presses, etc were developed: they not only save wear and tear on your body, they do better work, as a rule. Can they cause damage? Absolutely. So can any tool.

I use a practiced eye and steady hand to guide the billets through a bandsaw. I complete all the carving of each hand-carved instrument using gouges, planes, chisels, and scrapers.

The vast majority of my work is done using hand tools, but there are certain tasks for which I use the appropriate power tool, and make no apology for doing so. (By the way, I live eight miles outside a small town, and when I go to town, I drive…I don’t have a horse, and my time is too valuable (and limited) to walk that far just to satisfy some atavistic “back in time” quirk. I use electric lamps, etc., too, unless we have a power outage.) (sigh… OK, rant over…)

Lay out the Front and Back Shapes

I have a table of measurements I use, to lay out the front and back lines of the scroll and neck. The top of the neck is just over 24mm, the widest part of the pegbox front is 26mm, the distance from the leading edge of the nut to where the neck intersects the top plate is 130mm, and so forth.

I lay these out using a metric rule, a compass,  and a flexible straightedge. The main straightedge is just a stainless steel ruler with a cork backing that I bought from a fabric store. But I need a very flexible straightedge when I am laying out the curly portion of the scroll, so I cut a spiral strip out of a large soft-drink can (actually it was one of those oversized “energy drink” cans. Someone at work had it, and was going to throw it out, so I snagged it and made good use of the thin aluminum sides.) It is about 40mm wide, and long enough to wrap around the scroll, giving me a clean, smooth curve to scribe in with the pen. Aluminum flashing would work, too, but this was free. You can see the layout lines in the next step.

Cut off the Excess Wood from the Pegbox

I use the bandsaw, again, to trim all the waste wood from about two inches down the neck up to where the pegbox begins to disappear under the curve of the scroll. I leave the scroll and almost all of the neck full thickness, so that the billet will sit flat on the drill press table, and I can get the pilot holes for the pegs drilled parallel– perpendicular to the centerline of the neck.

Another nice thing about leaving the handle portion of the neck for last, is that it leaves me two parallel surfaces, so I can clamp the scroll in a vise, and use both hands to control the gouge, plane, saw, or other hand tool.

Layout and Drill the Peg Pilot Holes

Some people wait until the whole violin is completed, including varnishing, to drill the peg holes, but I find it too difficult to get them parallel with one another that way. If I can drill a 1/8″ pilot hole for each of them, using a drill press, so that they are exactly perpendicular to the center of the neck, I find it much easier to complete the neck later, than if I have to try to get them right with no flat surface from which to reference the perpendicularity of the holes. You’ll see these holes in the next blog post. So long as they get done before I cut the excess wood from the neck and scroll, I will be OK, because the neck will still sit squarely on the drill press table.

Carve the Pegbox

There are several ways to do this. A lot of makers use a drill to hog out the waste wood from the hole, and then use chisels and gouges to smooth and complete the work. I usually just use the chsels and gouges right from the beginning…one mistake with the drill, and the scroll becomes firewood.

I use a narrow, flat chisel to begin the work, and develop some depth, then use a wider, flat chisel to flatten the inside of the pegbox “cheeks,” and to deepen the box floor. I have to be careful to not go too deep. I have (once) cut so deep that, later, when I cut the fluting (volute) from the outside, I cut through into the interior of the pegbox. That is another good way to transform a nice scroll into firewood. Pretty sad when that happens.

I tend to begin by carving the outside of the pegbox heel… it makes me feel better about the scroll, if something about it is already starting to look like a finished scroll.

Four preliminary steps shown all together.
Here you can see all four of the preliminary steps, including the beginning of carving out the pegbox. You can see, too, the extra length in the five string fiddle pegboxes (on the right).

I will show photos of the succeeding steps in the next blog post. What you see above, though, is the beginning of all those nice violin, viola, cello, bass and five string fiddle scrolls you have enjoyed looking at.
