« Part 5: Linings Part 6 of Building Teardrop No. 2 series Part 7: Fitting and some gluing »

I temporarily attach the top and bottom plates to each other using painters tape. After drawing the rough outline of the ribs on one, I cut them out on my scroll saw.

Now I more carefully draw the outline using the ribs held in a better position. I’m using a thin sharpie held away from the ribs about 1/8 inch by a nut. I was thinking I would now whittle away the wood to the line, but I think I may go back to the scroll saw and cut very carefully just outside that line.

Seems the scroll saw is less likely to follow the grain and make a disastrous mistake. Using hand tools, I would probably use my little bow saw, then spokeshave them down flush once they’re attached to the ribs.

Nice progress Dave , and that’s using your nut!

As for the edge finish I wouldn’t be be game to use anything else but an oscillating sander and disk sander.

I agree with Dave, I think that trimming to match attached components is the way to go, can’t get a better fit than that.

Bear in mind that the top and bottom is supposed to overhand the ribs on these instruments, unlike on a guitar which is flush.

Here’s a picture showing the overhang I’m talking about. This is on my store bought violin, so is pretty standard.

I see what you’re talking about, Dave. I’d forgotten the overhang on fiddles. I think I’d still do final shaping after gluing things up, but that’s just my brain using the tools I have at hand. Something like a beading plane or scratch stock would let me get a consistent overhang while shaping things to the profile I was after.

Thanks again for taking the time to explain to us!
