I've built five prototype electric guitars, all with ordinary power and hand tools, like a router with masonite templates. The first, of aluminum and Poplar, broke under string pressure. The 2nd, of oak and masonite, still works. The 3rd was just too big and ugly to live. The 4th is big, heavy and ugly, but plays well, with four matched single-coil pickups and 10 humbucking outputs. The 5th of Poplar and Luaun plywood, not quite finished w/o an electric output, has more in common with a cigar box guitar, with its square-framed body.

More lately, I've been making custom wood guitar knobs, also posted on TulsaSoundGuitars.com. I've thought about writing DIY books on how to make guitars and knobs like these, and joined here to find out if there is any interest.
