Re: [atlas-craftsman IO] OT-how to test and repair DC brushed motors.

Thanks Jeff! First photo, last two digits 82 is the motor we've been talking about mostly. #83 is the other motor. They don't look too bad to me. ;) I'm also having a wiring or relay problem... I can hear the relay click. Nothing else happens. There are also a couple of limit switches in there, and a pair of momentary contact switches that are the Up & Down buttons. . Could be wiring, relay (which I have replaced because the original relay has a cracked open case) or switches. Could simply be corrosion, as this thing sat in an unconditioned shed for most of 20 years. I've got some wet or dry silicon carbide paper, and flint paper, not sure I have aluminum oxide paper... Emery is aluminum oxide. Do you know why it shouldn't be used? Too coarse? 

Got plenty of X-Acto knife blades, And I'm sure I could find a broken hacksaw blade. I mostly don't throw stuff like that away! I do not own a growler. Currently, doesn't look like I can afford one that I know works, either. ;)

Funny thing, found a cheap ladies nail care file/buffer thing in drawer under my desktop. Think I'll be using that to polish the commutator. Just the couple of strokes I took with it made the segment I used it one nice and shiny!

Got to drop all that and get us ready for her doctor's appointment this afternoon. More later!
