Good luck finding a twenty year old who wants to bake in the sun for forty years just to feel his knees pop at forty six.

Man, what makes your brain finally go quiet if it isn't the fishing?

Man, I gotta disagree with the hot take part but agree hard with your fix. The real problem wasnt that you oiled it, it was that you used 3-in-1 on a Dual and mixed it with old grease. That stuff gums up and turns into glue, especially in those old German tables that want a light machine oil or sewing machine oil at most. Ive brought back plenty of sluggish tables just by cleaning out the dried gunk and re-oiling the right spots with the right stuff, and they run smooth for years after. So oiling isnt the enemy, wrong oil and way too much of it is. Sounds like you figured that out the hard way with the isopropyl and phonolube, which is honestly the move for a lot of these. Not doing it at all just lets the bearings wear out dry, which is worse in the long run.
