So I recently changed to a laminated tail block and low and behold, I made it too thick when I glued up the last batch. Not a big deal- unless you are installing a pick up. I remembered seeing Frank Ford (I think) sharpen the back of a forstner bit and using it to drill from the outside of the guitar. He used it to countersink the bolts on a bolt on neck. Well, I am not a machinist, so that wasn't an option for me. Instead I came up with this thing:

The shaft is a long 3/8" bolt with the head cut off. I cut a slot in the end to allow the bade to set down in it. The blade is an old piece of a bar clamp I took apart years ago. I sharpened it on opposite sides so that it would cut properly while spinning (think router bit). I also cut a slot in it to accept the bolt- this way the two pieces would be locked together. But just for security, I added some superglue gel. It was a wonderfully tight fit and held rock solid. The hole for the end pin jack had already bin drilled to the required 1/2", so I wrapped tape around the 3/8" shaft of the cutter until it was 1/2". This allowed the cutter to be perfectly in the center of the end pin jack hole. The only problem with the thing- it cut better than I expected and I almost cut too deep.
Problem solved. I hope this helps. I am sure I am not the only person who has done this.
