I got a telecaster body and am interested in modifying it to a drop-horn tele. I plan to use a coping saw to get the original shape, a rasp and sander to smooth it out and a Dremel with a table router attachment to rout the rounded edges. I don't have any router bits and don't want to go to the expense of ordering a set of bits. I'm curious -- does anyone knows what size bit I'll need for the rounded edged?
