The motor is unnecessary. My jig is hand crank, and I can wind at about 120 turns per minute comfortably. I built my jig out of pvc, all-thread, and string, and the only tools it took were two pairs of pliers and a $4 hacksaw. I also constructed it in a dorm room in one afternoon. It will accommodate coils up to 14 in. in diameter, and length is only limited by lack of assistant to turn the crank.

I like this rig, it looks very easy to make. It's just that It's made out of PVC which I don't have, which means I would have to buy some. I've already spent 250+ on this coil, I don't really wanna spend anymore. I'm broke, just paid college fees and next semesters tuition :D. I think I'll just have to make my crappy hand winding technique work. Unfortunately, someone working in my dad's buisness decided to move my coil to the back to get it out of the way. In the process, he bent the outer ring of the primary, and knocked several capacitors loose from their mount, forunately the electrical connections between them are still good, but I'm basically going to have to rebuild the whole thing bottom up. I just hope I get it right this time, I want to see some success !

Russell Haley, looks similar to the kind i made, I just used 2 wood triangles, and a wood board. Right hand would turn the pipe, left hand would place the wire, and was able to coil a 2ft 4.5" out of 28awg, under a hour.

how did you keep tension on the wire? Also, the copper wire I'm using to connect spark gap to primary is rather thin, at around #18 or 20, is this a problem. The wire is insulated in some heavy rubber and I'm not sure what device it originally came from.
