That's an interesting idea to use motor oil as a finish. I'll try that.
Making progress on the Harold Hall grinding table. I did a boneheaded thing and ordered the wrong size dovetail cutter for the slides. So while waiting for the correct cutter, I got on some other parts.

Basically have the lathe tool grinding accessories done. I am panning to do the drill bit sharpening attachment at some point too.
The adjustment knobs turned out very nice.

The increments were made on the lathe with a “V” held side ways in the tool post. A piece of paper tape with 30 increments wrapped around the lathe chuck. Each increment got three cuts, adding 0.002” depth for each cut. At the end, a very light skim took off the burrs.
The lead screws have 32 threads per inch. Each increment on the adjustment knob is 0.00104” (doing the math).
