Looks good. What are you going to use to insulate the windings?

Hi Keith,
I used a 3M tape that looked a bit like shipping tape. Was long enouth ago that I don't know where I got it. Whatever is used has to be petrolum proof. I got a lot of my stuff from a local electric motor rewinder. Reworking a magnito ring is a slow process to the point that I gladly pay the vendor's price for one.

1. I lightly sanded both sides of the copper tape to clean it..
2. I installed insulating tape on both sides of the copper and trimmed the excess with a single edge blade.
3. Then wound the coils, shimming the take up "spool" so the coils fit on the coil ring stub snuggly.
4. Wrap the coil with 1/2 inch cotton tape (from my friendly motor rewinder).
5 Install the coils one up and one down (to make ac current) and solder them togerher.
6. I took the assembled product to my friendly motor rewinder to dip in varnish and bake.
note: I only got 24 winds of each coil vs. 25 origionally. It didn's seem to matter. Get as many as U can.

I did one once. Sprayed the "ribbons" with Dolph brand insulating paint. I think is was probably Glyptol (sp?) Then used cotton tape, soldered it all together and used the same insulating paint for the whole thing.

I agree it is a lot of work and now would pay someone else to do it!
