I am so lucky having a first class electric motor shop less than 30 miles away, Allen Electric what a great bunch. They pressure dipped and baked the coils, and wouldn't take a penny. And by the way, making a punch will make the cutting of the insulators under the coils a lot easier.
That's cool Bob! A valuable service to you and they wouldn't take any money... Guess where you'll go next time you need an electric motor. That was really nice.
I like that punch too!
Bob: Nice work. What material are you using for the insulating washers? thanks, jb

I would check the mounting surface of the mag ring, being sure it is metal to metal contact with the shims and/or block.
The paper is from a roll that was used to line the insides of a rail car. The roll is about 8’ wide, .018 thick and tuff as heck. The roll has hung in the shop for years with no ill effect from East Texas humidity. It has made countless gaskets, even pan gaskets by using 3 layers. You might check at your rail yard, with the folks that prep the box cars. Thanks for the heads upon the mounting surface. Wouldn’t that be a bummer to get it all back together and not have continuity.
Thanks Bob and Mark: I used .020" thick fish paper from McMaster-Carr. It's really a bear to cut and may be overkill compared to what Bob is using. Once saturated in the varnish I suspect even a writing tablet backing cardboard would be ok, but I'm not recommending that. Nice thing about the fish paper is having it on hand helps if you ever need an odd sized electrical insulating washer or an emergency brush plate insulator. Best to both of you, jb
