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.
