    12" long drill bit with a 1/4" diameter. There's a special name given to this bits, but I can't think of it. Something like marine bits or shipbuilders bits or something like that.

    What you do is you drill at a very shallow angle.

    I know them as gun drills.

    As you angle the bit from the pup cavity to the control cavity, I'd put a few layers of masking tape on the top at the far (bass-side) edge of the pup route, so that you don't mess the top if you slip.

    My mate drills a hole from lead jack to pup cavity via control cavity. Gets it all in one.

    It's called an aircraft bit. It's a long bit.
