sweet. Do you fancy doing some sort of write up about it? I'd love to know how you did it without the jig. My Brother built one many years ago but made a jig (out of wood but it worked and didn't catch fire).
THeres a fantastic set of videos on youtube with a guy who builds a frame without a jig, step by step process very interesting, have a search, if you cant find it hit me up with a PM and il have a dig around
