I'm tempted to get a pair of these. I have the revolver jig right now but the fact the rods are held in by a grub screw causes them to dig into the rod; and after a few uses you find your coils getting caught on the jagged edges it leaves...it gets a bit annoying. I should hunt through some local shops to see if they have them in yet.
It's not hard to make a coil wrapped with any metal form tool tensioned after wrapping, including the coil master. Wrap the coil, grab both of the coil tails at the same time with pliers, get a grip on the metal form it was wrapped on and simply pull the tails away from the form (90 degrees) slowly to make them tight around the form. The wire will slip on the metal form IOW. All the individual coils will have the same tension or very close to it. If you pull it with a little extra force it can also help pull the coils tight against each other if you didn't wrap them all making contact with each other perfectly. Kanthal A1 is a lot stronger than you might think.
