Jazz bass Mod becomes Build?

[Trevor Davies]

I like it! Simple and effective. Do you know what angle that is?

The angle is 15 degrees. This gave me a drop of about 10 mm into the body for every run of 40 mm across the body!

I use a 4 mm drill bit.

FYI - When I made it, I clamped 2 (Jig sized) bits of wood together, slightly staggered so that I made 2 jigs at once. The idea was to prevent tear out when the drill bit exits the first block.

I like this! Simple and effective. I actually bought a jig for $10 on Amazon with the same angle.



While it's got the same angle, the smallest drill bit that it works with is 6mm...which seems a bit big to me. I have a feeling that a part of the excessive tear out that I had may have to do with using a relatively large bit. What do you think?

I have something similar for woodworking!

Yes, I think 6 mm is too big (and 5mm!). I find the size of the body surface hole is too big and therefore it has to be started further under the bridge area. My original one was using a 5 mm bit, but I have since changed to a good quality 4mm bit.

I have found that my pine wood jig wears out quite quickly and the guiding hole becomes too large on the section that joins to the body!
