I might be looking at a Bridgeport this weekend, don't know the exact
model number yet. I do know it's got a 208 3ph motor. The pic shows
it's been painted, the bare parts are "brownish" but don't look too
horrible-

What should I be checking on this beastie for wear etc. ?
Thanks,
H.

I think that the brownish stuff looks suspicious, I would
investigate. It is not where it should be. If the painted surfaces
were brownish, and the bare metal were grey, I would like it better,
but it is the exact reverse -- bright paint and brown bare metal.
Makes be a little suspicious.
The Spray paint job on it looks very hasty.
The motor is not the original and one begins to wonder what happened
to it. Did it burn out? What else is in trouble if the mill was that
overloaded?

He didn't even tape the knee ways before he painted it. You can see
paint on them.

Exactly.
Probably painted right over the dried oil.

Well off the bat it is missing the x table lock. That rust doesn't make me
real thrilled from here.
I don't see an oiling system on it. I guess the older ones didn't have it
but oil and working wipers are vital to the health of the machines ways.
These might get greased. I've never actually touched one this old.
I'd look close at the sliding surfaces. There is scraping and flaking.
Flaking is the bigger divots that holds lubricant. Look at extreme end of
travels then compare how the ways look in the middle of travel.
Check the taper to see if it looks okay. Run the motor and listen to it.
Try the power feed both up and down in all three ranges.
See what kind of lash you have in the lead screws. Check it in various
places to see if you have signifantly more wear in the middle than at ends.
Extend the quill and see how it deflects when you push on it. I think
Gunner said 0.002" would be about max back a while. My memory could be
wrong.
Reasonable price is whatever scrap goes for and up. ;)
I'm not impressed by the sloppy paint job. Warning Master Robenson.....
