ok, I finally banged that old shaft out. (insert joke)
Got the new motor installed and it works very nicely. I agree with prior comments that it may not be uniform as far as going up and then coming right back down, but it works, and its cool.
Cliffys installed, (the cliffys really saved my wabac ramp. It had a huge chunk missing and the left cliffy took care of it), motor installed. Way more hours than I'd care to admit.
All I need now is the new legs I ordered (the machine is not level, and I can't get the feet to move even after soaking with pb blaster for 2 days), NVRAM (also on order), oh yeah I got the new yellow flipper bats (and a full rebuid kit just to have on hand). I need to consider upgrading the revision from 1.10 to whatever the most current is, and boom I'll be as good as I could hope to be.
edit : oh yeah , I need to install the new Lion I have in the back box, and finish rebuilding/reflowing solder to each of the boards in the back box. 2 down, 2 to go.
