Is there a quick way to square a swivel vise to the direction of
travel? I can get moderately close with a piece of paper and a piece
of precision rod stock. To get closer I have to cut something and use
a depth gage of some type horizontally to measure the difference from
one end to the other.

How about about tightening it down without it moving? I just tighten
a little and paper it. Then a little more and paper it again, etc, to
the point where I have to make final adjustments with a deadblow
hammer.

With one of my screwless vises I slap it on the table, square it up
with a machinist square, and clamp it down. I may have to make a few
hammer adjustments, but its already really close, and it doesn't move
enough to be noticeable when I tighten it in place with clamps.

Actually I so rarely need to use the swivel part of the vise I was
thinking about removing it from the mill entirely... maybe throw it on
the noname mill drill (if it isn't too tall or maybe with swivel
removed) and leave a pair of screwless vises on the RF-30 instead.
Take a little time to square them up to the mill and each other and
leave them on it.

Start indicating with your indicator in the middle of the vise jaw and set it to zero. Then move the table left and swivel the vise till the indicator again reads zero at the right hand end of the jaw..

Shouldn't take more than 30 seconds or so.
