Teardrop fiddle build

Getting moldy

I've had this one in mind for a while and since the current crisis is giving me some slack time at work, I figured I'd just go for it.
A teardrop fiddle is a violin, but shaped more like a teardrop than an hourglass. I'm making this up as I go, so hang on for the ride!

Tonight I made the mold for the body. I used a scrap of 3/4 inch plywood. The mould is used to hold the end blocks and to shape the thin strips of wood that are called ribs. I cut most of everything else I needed in my shop and will bring the whole thing to work. Providing the current unpleasantness doesn't keep me away from work, where my tools for this live, I should have it done in a few weeks.

The mold, wood for the plates, and a violin neck that I had laying around.

I created the shape by tracing one of my violins, preserving the width at the waist and tapering it to the neck.

Other than the obvious shape difference, is there a difference to the volume or tone or playability of a teardrop vs. a normal fiddle?

Theoretically I think it should be not as loud. Basically everything that led to the shape of a violin was to make it louder. And since mine hasn't the upper two bouts, or shoulders if you will, the player will have to hold it by the neck to place the instrument under the chin. It should also be easier to play the higher notes on the fingerboard because of the lack of those upper bouts.

Much of the progress will depend on my workload at the shop. There's not a lot going on with the schools closed in our area. Nobody's breaking their instruments.

End blocks

The rough end blocks, made of a chunk of 2×4 are glued to the mould temporarily.

Then they are carved to curved shape to hold the ribs of the instrument. The ribs will be glued to the end blocks.

OK, you've got my curiosity in gear. Do the end blocks become a permanent part of the instrument? Sounds like it, they are temporarily attached to the mold, then glued to the ribs.
I'm waiting for the next post.

The endblocks stay in the instrument. The neck attaches to one and the tailpiece for the strings to the other. I'm going to put up one post a day if possible.

I've had to bring the project home to complete because the shop is bneing closed by the state, or at least that is very likely at this point.

Interesting, Dave! Hope you can get it built at home.

The Ribs

The ribs are mahogany measuring about 18 inches long x 1 1/4 inches wide x 1mm thick. I bent them using the odd object in the upper right of the photo. A heat gun blows bvery hot air through some plumbing fittings to heat the brass nipple. the moistened rib is held against it and gently bent. I brought 7 ribs to work to bend. I managed to use them all up, but came out with the 2 good ones I needed. They crack if you work too fast.

Then, using a bunch of small clamps and the holes in the mold, I glued the bent ribs to the end blocks.

The Plates

I'm making the top and bottom (front and back) plates from mahogany for the back and pine for the front, (it may actually be poplar.)

I cut deep kerfs in the edges and cut the rest by hand.

Wood Tool Hardwood Wood stain Lumber


Then I glue the edges together.

There are several reasons to create the wide plate this way, but for me it was

a) I didn't have wood that wide

b) The hope of getting a cool, bookmatched grain pattern.

Are you going to hand plane the assembly, or electric sand?
Resawing has always been a difficult task for me, never works out well, even broke a bandsaw blade once. Hand sawing isn't any better, I usually end up with one usable board out of the two.
Is there enough material there in that glue up for a top and bottom?

Because I brought it home, I ran the plates through my thickness planer. If I had stayed at work, I would have tried very hard using just the planes I have there.

I used a table saw to do most of the work and yes, the center surfaces end up very rough.

There is enough material, though the mahogany could have been an inch longer for security. It's just long enough!

Linings

Linings are strips of wood that thicken the top and bottom of the ribs to aid in gluing the front and back onto the ribs.

They have to be bent with a heat iron just like the ribs. I also discovered that mahogany is too brittle and dug out what may be oak or poplar to use.

The linings are clamped for gluing with special lining clamps.

I've seen those special lining clamps, in the most unusual place, the dollar store has them.

How thick were the linings, Dave? Roughly same thickness as the ribs, or are they thicker?
