No Dremel of machining experience required. Rough it out with a large file, and then finish the job with a simple jeweler's file from a hobby store. Matt's posting about proper hardening is an excellent and simple touch to really make it last. I must have a dozen of these custom spanners, and it's much easier than machining sockets if you don't have that kind of experience. Chas
