I don't have a supplied mounting bar. Just the digimatic. The hard part
for me is how to attach to the round part with the hole in it that goes
up and down. The photo Pete sent me shows a pin that goes into the hole.
I guess I could make a pin that is a very tight fit into that hole and it
would work. The other option is a two part clamp that would grip that
round part.

The pin that goes into the hole has a slot milled into for about half it's
length. On the end that goes into the hole, not the end that attaches to
the DRO. There is a setscrew at an angle that spreads the split and expands
the split end inside the hole. E-mail me if you want a good photo of the
arrangement.
