You're good. Seems one of the shims has worked loose under a foot. And, changing tool geometry has made a world of difference. No chatter marks now! 
Tooling fixed, bearings fixed, belts and gibs tightened.. I'll dabble with the tooling some more as finish has suffered (tearing in 1018). Read somewhere that swinging the tool out 1/4" and sliding a stone under it will true it.
About the table ways, you are spot on. I noticed the left end of the near trough seemed to have a surplus of oil. Bending over to peer at it, I also noticed that the foot was moving a little. Shut the machine off and found I could see oil squishing out when I pressed on the table. Not good. I think I'll jack up that one foot and try another shim under it, rather than going through the leveling process again. Lacking a level, I had removed the table, filled the troughs with water and used a depth mike. The other three feet seem solid and their respective ways are wiping like you'd expect. Something has gone wrong with the stack of scrap that I used for shims.
Another problem occurs at the end of a stoke when the table stop climbs up on top of the dog. The table lifts upward. There has been a repair made, a glob of braze laid down on the dog. It's a bit tall and looks like a file will make short work of things once I have the dog in a vice.
