It's possibly done by the grubscrews (No. 48), but there will likely be some correct order to do the adjustment. Probably slacken the main mounting bolts, adjust the grub screws, then re-tighten. You may need to fully remove the headstock to work out how they adjust, but you'll have to be aware of any shims that might have been used.
Thanks, that will be a big job.

I would think I need a test bar say 12" long to center on the Tailstock center point?

The mount bolts are hidden at the back by the drive motor, so that will need removal also.

All the best and thanks for your comments!
