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.
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.

Two New Five-string Fiddles in the Works
My wife has been after me for some time to increase my output of 5 string bluegrass fiddles. (She’s probably right, but there are so many other things to do!) So…what to do? I made two new molds, a little broader in the middle bouts, which may improve the sound even more. I installed blocks in both molds and hope to build one five string fiddle of Oregon Myrtle-wood with a Port-Orford Cedar top, and another five-string fiddle of figured maple with a spruce top.
I had belly surgery last month (gall-bladder removal) and I am feeling much better. It makes me wonder whether that has been the main source of much of my “don’t feel good” problems for years. I feel so much more positive about work, lutherie and life in general, it is pretty amazing. (And, no, I am not on any “feel-good” meds, in case you are wondering… although, I’ve got to say, after the few days of Oxy-Codone, I can see why people get addicted to the stuff. But I got off it just a few days after the surgery, with just a few times going back for a day or two, to get over a hump, so to speak, when pain became a problem again.)
Progress Thus Far:
So: I have bent the ribs for the figured Oregon Mytrle-wood/Port Orford Cedar fiddle, but still have to join the plates both front and back. I installed the center bout ribs last night, and hope to get the upper and lower bout ribs installed today.
The plates for the Maple/Spruce fiddle are already joined, but the ribs are only cut– they still need to be thinned down to 1mm and cut to 35mm width. If I can get that done today, I will heat up the bending iron and try to get the ribs bent, and the c-bout ribs installed. After that I can work on getting the willow linings cut, bent and installed.
Both fiddles need the neck-blocks cut to shape, to prepare for carving. Neither have any plate-carving done, nor purfling, f-holes, etc., of course.
Follow along as I complete the builds. If you decide you’d like a private look at one of them give me a call or an e-mail.
The intent is to have two new five string fiddles ready in time for the Marylhurst University Musical Instrument Show in the Spring ( April 25th and 26th, 2015) My problem is that I also realllllly want to have a new hand-carved upright bass ready in time to attend the International Society of Bassists (ISB) competition in Fort Collins, Colorado, in the last week of May/first weekend of June. (Too many goals…need more energy and time!)
One drawback to the competition goal is that (I think) I will not be able to post progress reports, (photos, anyway) until after the competition. Ah, well… I’ll post other stuff, I guess.
