OK, I need some help. I have a Jet Mini Lathe that appeared to have some bearing problems. When turning at ~4000 rpm for about 15 minutes, the headstock would get quite warm, in fact uncomfortable to touch.
I replaced the bearings hoping that would resolve the issue but upon removing the existing bearings, they appeared to be fine (smooth operation). I replaced them anyway but the headstock appears to heat up at about the same rate.
In addition to the lack of improvement, the lathe is noticeably louder now and the noise sounds like it is coming from the thrust washer (I think that's the name). The noise can be reduced by tightening down the hand wheel but I'm now wondering if that's where the friction/heat may be coming from.
Any ideas or thoughts? Should I consider replacing the thrust washer?
I have another Jet Mini Lathe that shows no appreciable sign of heating up during use.
Thanks in advance for the help!
