I have wound a couple pancake arms for my T-jets, and they have come out very well, I want to start trying to work on some that would be Fray type legal, I have found that for the winding process a bobin tool like the fishing fly builders use works very good. There are types that have an extended tip & you can lay that wire wrap right in place on the stack easily, and it goes pretty fast. Does any one have a chart for the wire diameter & length required to produce a specific ohm after the pole is wound? if so I would really appreciate that info, also any tricks or tools to remove & attach the com plate would be appreciated.
I made a crude little press to reform the tabs but you have to be soo careful, I know there has to be a better way. I use a brass sleeve to center the comm plate on the stack, then remove it afterwards.
Also if anyone knows what to use to dye the armature stacks with, that information would be nice to know as well. I just got my first lamination stack done, checked the shaft & now after a little lathe work its near perfectly round. I may just paint this one on the ends but it would be nice to dye it like some I have seen.
One other piece of advice from a novice for rewinds, I have had really good luck balancing my arms with epoxy afterwards, and they run very smooth, get yourself a watch makers poising tool, I picked up a really nice ruby jaw unit for $15 from ebay, Just take your time when you balance, I blow on the arm with a straw to rotate it. I practiced with modeling clay until I got the "expertise" & nerve up to start using the epoxy.
