With the way tubes locked down, the critical thing is the 'angle' across the two way tubes is the same at both ends(twist). That big set screw is adjusted to achieve that.
A way to check that is the tailstock center point aligning with a drive center point on the quill, then moving the drive center to the top aux shaft and moving the tailstock to the other end. If the points do not align(front to rear), the way tubes are 'twisted'.
I’ll have to wait until I get the headstock refurbished to do that test. I did put a level across the way tubes at each end and they were the same.

Some 1000 grit wet sandpaper and the table cleaned up nicely. Straight edge shows its still flat.

Thank you very much, I'm pretty happy considering the condition it was in.

Other than oxidation and saw dust the only thing I see missing is the two screws and wide tinnerman nuts that secure the vent plate.
Examination of the speed control is needed.
I think it will clean up nicely! That rusted motor fan shroud will be a challenge. Evaporust/rags may be the answer.

Thanks, I have them. Found the nuts in the motor housing

Insides also look like great progress will be attainable.
