This machine caught my eye on eBay, it was only about 45 miles away. It looked pretty good in the pics and had all the necessary bits with it bar the steadies so I went to look it over. It was still powered so I ran through all the controls, everything worked and it ran at full speed without making any strange noises. I put a 14" long bar in the collet and tugged as hard as I could on it up and down and my 1um dial indicator didn't so much as twitch. Then I ran it slow and put the indicator against the camlock mounting faces, and this is where my heart sank.

It's showing 14um swing on the face of the camlock, that's just over 0.0005", and 8um on the camlock OD taper, about 0.0003" with a similar amount on the ID collet taper.
I guess it's had a pretty heavy crash to bend what is a fairly chunky spindle for a 2hp lathe.
I've already bid on it before going to view, and it's a fairly low bid so I expect it to be surpassed. If not I'm going to be faced with either parting the machine out for bits and scrapping the rest or looking at ways to repair the spindle. What are the options - grind in situ? It isn't much to grind a few tenths surely and the machine does have a taper attachment. What would your thoughts be on this?
