I like to have an excuse to dig out my old coil winding machine that I
brought back to working order from a seized rusted mess combined with
mice
nest that was in a leaky shed for decades.

That explains a great deal right there. Otherwise, motor rewinding is
a difficult and obscure art, at least for most of us. I've been
building electromagnets for demonstrations at the science museum, and
it doesn't take long for even the simplest coil to turn into a mighty
mess if you're not careful.

I have a vacuum pump that's essentially integral with its squirrel-
cage induction motor, and the stator overheats. The fellow at the
motor shop gave me some insane estimate of several hundred bucks to
rewind the thing; I'm ready to try it myself.

You know, I borrowed a vacuum pump the first time I did some A/C work but I
later found I could buy new surplus rotary compressors designed for window
AC units for $5-$8 and they pull a stronger vacuum than the real vacuum pump
I had! Pegs the mechanical guage all the way down to 30 in/hg which is
plenty lots of things and the price is hard to beat.
