HALLELUJAH I finally found a good motor wire insulation remover

I'm done with facials, thanks Don!

You've certainly dug deeper than me. I will probably give it a go this weekend.

Well, since you didn't want a response from ME, I'm not gonna tell you the secret special method.

HA HA HA.... I feel guilty! You provide a lot of helpful information and I don't feel I am providing anything in return!

So you've been using this method a bunch now?

[donhuff]

Not really a bunch. Just when I have a lot of motors to do at one time. I'll put the wire bundles in the solution to soak while I am tearing down the motors.

I mostly still use the hot Lye process to do one or two wires sets, mostly because it is quicker.

To do what you are planing, I would use the Lye.

Sorry, had to do a second post cause the power went off.

But I would use the Lye only because it is quicker. If your not in a hurry, do the antifreeze. And remember that it will work without heat. But it will take several days for it to get really clean. Just fill a cup or something with the antifreeze, place a piece of thin ply scrap over the top with three holes in it , and stick the wire bundles through the holes and into the antifreeze. Set it to the side and leave it for a few days or a week. You can check the progress now and then , and it might help to use a wire toothbrush to clean the swollen insulation off and then submerge and soak more to remove the remaining varnish. It WILL eventually all turn a loose and can be wiped off.

Be aware that the solution will "wick up" a little, 1/8th to a 1/4". So don't put it so deep that the wicking will remove it past the end bell unless you can be sure to get heat shrink all the way up in there to cover the naked wire, so that you don't create a short between the three legs where they all get close to each other.
