[Milsurplus] dynamotor repair

[J Forster]

Hi David,

I meant heating it briefly just to remove the brush holder, which won't work
IMO. You are suggesting a bakeout, which is a different thing. I'd be
reluctant to bake a dyno complete with bearings though. If the brush holder
and casting are separate, go for it.

Best,
-John
