The tensioning rig isn't a bad idea, but I'll likely continue to do it by hand anyway. I made a hand cranked mandrel, like his, that lets me wind almost two foot long coils at one go. The rod I wind around is a 5/8" steel bar, that I drilled a hole through with my drill press.

I've also looked at The Ringinator and several other ring cutting rigs. The Ringinator doesn't even come with the drill you need to drive the thing, for a cost of $450.00. For about $50.00 I can buy a jeweller's saw and the chuck for it, clamp it into my Dremel, and build a clamp that will work like The Ringinator. I figure that I'll either feed the coils through a piece of copper or plastic pipe with a slot cut into it, to take it past the jeweller's saw blade that will cut it.
