Repairing Atlas 10" lathe

[bogstandard]

Ross,

Glad things turned out well. There is always more than one way to skin a cat.

If you can still have easy access to the ground off part, I would go around the square joint with a centre punch, just to make the gear a little more secure.

Don't go having nightmares about the unequal pull off pressures just yet. I would wait until you can run the spindle up before taking any rash measures.

Plenty of oil for lube, then let the spindle run for ten to fifteen minutes, checking on the bearing caps to make sure that things aren't overheating, warm is OK, hot is not.

After that time, let it cool down for an hour or so, then recheck to see if it has the uneven drag.

You have done so much work on it, it could be something as simple as a bit of oil varnish in either the races or on the rollers that is causing the problem. It only takes microns of thickness to show up as uneven.

If it is still at fault, then investigate.
