« Part 8: F-holes Part 9 of Building Teardrop No. 2 series no next part

The bass bar is made of pine, and is located so that it will sit under the ‘bass’ foot of the bridge. (On a violin the G-string is the bass side) According to the book I have, the bass bar does not run parallel, but is canted ever so slightly. I’m thinking this helps prevent cracks in the top that run along the wood grain.

Where in a traditional violin there is a long process to fit the contour of the bass bar to the arching of the top, I have it easy because my top and bottom plates are flat.

Here I have clamped an over-height bass bar which I’ve glued in.

And here I’ve just about finished paring the bass bar down to its final form. I’ve now moved the project back to my place of work, so the lighting is better and I have my good tools to use!

This project seems to be pretty intricate and exacting. Good work.

Are there rules about the thickness of the bass bar along its length, Dave? It doesn’t look like it’s uniform, but that might be a trick of the camera angle.

Thank you.

It can be very exacting work. I think I’m playing things a little fast and loose. If you ever watched actual violin makers, you’d think they were Michelangelo sculpting the David. Their instruments are beautiful. To me, mine are part of a learning process and fun.

There are rules and there are exceptions. Or perhaps there is a standard, and a list of how the instrument is affected by deviating from the standards.

The thickness of my bass bar is the same during the whole length, but the height tapers down on each end, basically starting from the terminii of the F holes. The height is close to 10-12 mm in the middle and tapers to probably 3 mm on the ends. (I only know the metric there because it’s the system I used for that part.)

Thanks. I’ve learned a lot about instrument making by watching videos of others doing it, even guitar luthiers. There’s a lot of things in common between the two.
