You got my vote. I'd like to see that aslo. In my early years I helped set up machines but nothing that big. Cool stuff. Mr Mikey.

Note it's secured with planer jacks and screws to a T-slotted base. This monster might have been driven from below! Sensible, open the gap, crane in a blank, close the gap and set to whittle away.
Unsure about the motor endbell visible to the left, certainly connected to shaft holding the gear.

I agree.I always thought they made those in 2 parts. perhaps they are 2 peices.

One piece, the slot in the middle is for run-out of the tools.

Ive seen them in 2 peices ,I presumed for setting back lash when needed to do so.

What appears to be cutter heads, the inclined 'toolposts' is a very precise yet easy adjustment in simultaneous centerline and diameter correction for setup, independent of the 'cross slide'.

100,000 tons?
I think maybe an extra zero slipped in there!
