Need Help with 1717 Wires

What three methods did you use?

The varnish is some really high temp stuff, so it takes alot to burn it. As mentioned, a small butane torch or even a larger propane torch would do the job.

Keeping the heat out of/off the motor is a precaution you must take.

One thing that might aid this, is to strip more of the insulation off, so the damp cloth makes better contact with the wire. The "insulation" is just heat shrink.

Burning this is going to leave a crusty mess, which also has to be cleaned up. I would suggest a fine bristle brass brush for this job. Brush the crap out of the ends after burning, and clean them up as best you can. The cleaner the better.

If it doesn't come clean the first time, repeat step one with the torch, then brush again. Rinse, lather, repeat............until the varnish is gone and they are clean.

A good, clean, solid 1/8" at the end of the leads will work.

Dab some soldering flux paste on the wire ends before you begin soldering. It will help the solder flow better.

Once you get a good "tinning" on the lead end, apply heat shrink to the extra exposed lead.

I have rewound a few outrunner motors and always found this part of the process to be a challenge.

It can be done though. You just have to be careful and neat with your work.

Best of Luck.

I tried heating the wire with a torch, scraping the wire with a razor blade and using a aspirin tablet under the wire to burn off the coating. I will admit that if I really took my time I could probably get the wire clean enough to tin it but I just wonder if I should just leave it up to a pro and not do more damage.
