I can get a very good deal on a RoboForm 200 with a C axis and a 20 place electrode changer.
It is setup for Erowa tooling and we have all 3r stuff.
I do have a chuck from a RoboForm 20 that did not have a C axis and only had a 4 place changer mounted on the side of the tank.

Is there a chance the chuck I have will work?

And do the fingers in the changer arm and carousel need to be changed?

In other words how much is this good deal likely to cost?
