Guys that re-build starters and generators professionaly most likely have paper type insulation material for the fields inside the case. Probably thinner than those you have? Plastic butter dish lid material? It most likely needs to withstand heat and water. Junk electric motors? Maybe a electrical supply shop sells bulk insulation material? You'll find it Muley!!!!
Yep Cap'n if I can source the sheet phenolic it will most likely be Dremel work-one at a time. If I can make it work, while the project is goin mebbe I can work up a couple sets-there's 4 insulators per switch-2 lg, 2 sm. It'll cost ya big time supersonic..
Where the heck is the professor, still on the quail hunt? I bet that SOB knows where to find the materials..
I hear ya Cap'n! Any idea how the SOB got oil filled?
It was water tight when new, 60 years back!, most likely as the bushings get lazy over time and the rear main suffers the same fate, it seeps in through the shaft seal. The nose cone acts as a catchers mitt for the flinging oil, directs a few drops over time to the shaft seal ..... no idea where that one came from, I never used it and glad it's got a new owner!.
