S/Seel and the minilathe

You'll still get galvanic corrosion with stainless in aluminium..

Only if it's a submerged clock or it's used in a very humid environment without oil.
I have Aluminium parts with Stainless pivot pins on guns I built 10 years ago and more with no issues ;-)

That is very true, however corrosion was the only reason for not using a mild steel, and I was highlighting that there is more to material selection than obvious corrosion.


As for answering the OP's material selection question, it all depends on speed.
I'm guessing a clock spring winder isn't going to be running that fast, or see that much use, so I'd just use whatever I had lying around.
