Let me see if I can find a longer youtube on it . Mine is over at a bud's place , We were thinkin on doing some automotive alternator windmills , but life got in the way . I installed some new power in our local NAPA auto parts for their new alternator tester? when he said gimme a bill I told him I wanted the old tester , we were gearing up & then .....

Here's a pretty good tube on one , these folks have a couple of the l'll buggers .

Ebay has a couple but their pretty darn proud of them .

I picked up a armature lathe many years back at a yard sale . I asked the guy how much for te armature lathe & he said " is that what that is " . He gave it to me cause I was the only guy out of 50-75 people that knew what it was . Have used it a fair amount over the years .

If ya ever see one of these at a yard sale & ya can get it cheap their on the handy side .

I've always used scotch pads instead of sand paper over teh years , their a bit cleaner then sand paper . Here's some scotch pad info that some of ya may find interesting
