Travers part #61-171-001. $77 + SH. Looks like you could make one.
But it also looks like it wouldn't work on a drill press that has a rack
on the side of the column for table raise/lower. Even if you modified
it to mount around the rack, it couldn't swivel on the column.

Make a two-art collar. The inner part is a 'C' with a gap to
clear the rack, and the outer part turns freely on the inner. One or
the other would need a flange to support the outer on the inner, of
course.

Enjoy,
DoN.
