So the chassis is sleeved (I think with bronze, not sure though), machined a hair off of the shaft.
It's silky smooth now.
Everything is clean and bind free.
One issue I had though, is the slot in the one arm wasn't big enough to take the new bushing. In fact it wasn't even big enough to take the old worn one. So I reamed it out a little bit, used the old bushing upside down.
I figure if for some reason it wears and it opens a bit, i'll just swap in the replacement bushing.
Oh, and the extension spring I bought, apparently that is for card dispenser, doh.
I just re-used the old one with a new hook bent into the end.
Smashes home runs so fast sometimes I can't even tell where the ball went.
Have to give everywhere the ball goes a good cleaning, then I will install new balls.
6 balls right? At least that's what I bought.
