I need a "how to" lesson

Hello fan friends. I recently acquired an 8-inch MESCO battery fan seen below:

The fan was missing one oiler which Darryl Hudson recreated for me. Rick Powell stripped and re-japanned it and Ron Bethoney restored the brass. Peter Blackman provided the 22K gold OFF / ON decal.

I re-assembled the fan below and it ran fine on the highest speed (bypassing the speed coil).

I had examined the speed coil previously and discovered a break in the tiny wire which I soldered.

After repairing this break, I was still not able to get readings on the second and third speeds. There has to be a break somewhere else in the resistance wire, though I cannot seem to locate it so I will have to rewind the tower.

It seems to me that the rewind process should be fairly straightforward though I have no idea how to proceed hence the title of this post:  How to do a rewind?

I hate to bother the good folks on this forum who do rewinds with such a trivial job. Can someone direct me to a source for providing some instruction on how to do a rewind like this please?

Resistance wire is a type of stainless steel, which means it won't solder properly. It needs a mechanical connection instead. Check all connections before you go to the trouble of rewinding.

Good to know, Bill. Thanks. I unwound one turn of that broken wire and made the physical connection but still no go, Bill. I don't have a clue about what to do next.

There is some kind of coating on the wires. Clean it off with lacquer thinner, acetone, or whatever works and use your ohmmeter to locate where the break is. Then do the same thing at the break for a mechanical connection. Maker sure the connections from the coil to the switch and to the motor are solid as well.

Thanks Bill. I typically use a single edge razor to scrape the wire down to clean copper. I'm still at a loss to figure out what's going. I'm going to email you off line.
