Spindle Oil Cup, Oil Flow?

Ed,

Easiest solution is to add a low density felt plug to the oil cup. The factory did this on at least the 12" around 1967 on and recommended retrofitting older machines. Top of the plug should be about .03" below top of cup so that you can fill it until just a little liquid oil is visible on top (with the cap open, of course). You can buy a sheet of felt and an arch punch and make these, but unless you need a bunch of them or have some other use for the rest of the sheet and the punch, it'll actually be cheaper to buy them from Clausing.

BTW, if your machine actually has sleeve bearings as you wrote, and not Timken bearings, it isn't a 618. It could be a Craftsman 101.07300 but odds are 100:1 that it's a 101.07301.

I cut up some cheap corn pad plasters the type that have medical grade felt pressure rings on them to get my felts . To get the right size pads I turned up a mild steel tube to make a simple hollow tube punch & picked the cut wad out with a needle.
 
Just be sure that the felt that you use it pretty low density.
