Ok, I just don't see the purpose. It's a freaking swivel base. Why?

Keeps the vise in a known position on the rotary base, so the fixed jaw
is
always at a certain radius from center.

I'm not sure I do it, but I can see its usefulness, especially if one
were
doing a lot of one particular part (not in batches) over several changes
of
tooling and fixturing.


The base was keyed to the table. Not the vise to the base.

That shows you how rarely the vise needed to swivel. Does the vise itself
have mounting ears?

Yes, but I intend to leave it on the swivel base on this machine since it
always used for eyeball, and feel type cuts and drilling.
