Moving forward...
still missing split nut and gears for fine lead screw rotation.

This or similar is what I have in mind.... of course, not made of plastic.

And dead/live centre on the other side.

As for parallelism between chuck and sliding rods, I will try to use laser collimator. I need to achieve better than 0.1mm, 30cm away from chuck
