With how toxic cad plating is (and that it is original) I usually try to leave it alone.

Given the set has not ran in a long time I'd be leery of completely sealing the fly windings. Sometimes moisture collects in the windings and it takes a while running the set for it to boil out....Plugging it's escape route seems like something to avoid doing.

The CAD plating is removed easily and is captured in the solution. I think it's best to get rid of it once and for all.

Remember that I baked it prior to sealing.

Looking good! At some point I need to try dipping a flyback in Polyurethane varnish and see how it holds up. The Super Corona Dope MSD sheet says it's a modified Alkyd, which I'm assuming means it's a your basic Alkyd resin with Polyurethane additive for better flexibility/heat resistance. Also most Alkyd and Phenolic resins are moisture permeable, meaning they will allow moisture vapor to slowly pass through them.

Thanks Kevin.

Today I re-stuffed C2. I used some solid 22awg 600V wire for each lead to the terminals. I'll let the pictures tell the story.

How do you get such a nice clean cut when opening the caps? Lathe??

I use a band saw then true up the parting surfaces with my disc sander.
