So about a year ago I bought and restored an old McKenzie lathe which the group was great for helping me with the questions I had. At the time I didn't do much with the spindle bearings other than set the oil clearance with shims and plasti-gage. The lathe ran great for the last year and I've made alot of parts with it since I've had it running but just recently I've been getting chatter and it's been getting worse and worse to the point where today I measured .015" play at the end of a 6" part. The chatter was too much I had to do something About it so I tore into it did some investigating. I measured .004" play at the spindle at both the front and back bearings. I also took the spindle out to get a look at things and measure. The spindle measured nice an round everywhere I measured. The bearings not so much... they're pretty scored along with the spindle and the bearings are measurably egg shaped. The 2 numbers for the bearings where taken 90° apart, I took a few more measurements that aren't written down. All the measurements are in the pictures Along with pictures of the bearings and spindle itself. What do you guys recommend be the course of action? The bearings where measure with no shims installed and bolts tightened down.
