I removed the table tonight..and the screw is bent in two places, both
of which should be easy to straighten. Unfortunately......the bends
are on the wrong side of the nut, which is bolted to the top of the
knee, under the table. And the screw will turn, but only to the first
bend. Unfortunately again..it only will screw out in one direction, as
there is a flange machined into one end of the screw, so the
direction it comes out..is the one blocked by the bend.

The nut is held in with a couple of large screws, both directly under
the screw. The screw has to come out to get to the nut fasteners..and
it wont come out because of the bend...sigh. Now I have to figure out
a way to straighten it while its still in the machine, though fully
exposed. The nut is a long cast iron "tube" tapped inside for the
thread

If you can get to the outside of the bend, maybe a porta-power
bow-and-arrow sling would do it. Wrap cable (bow string) around
the ends of the screw (bow), secure, and insert the porta-power
ram (arrow) in between, against the bend. Pump it straight. Use
additional cables to maintain the integrity of the screw in the
mid points if necessary.
