    Pretty clever. I'll have to try make one. Is that one you made? You could set the counter weight to allow it to give the right pressure for drilling.

    Thank you everybody for responding to my post. It seems that using a backer is the way to go for now. What would be the best material for a backer?

    I've used that exact technique. Pain in the backside. With carbide it's just too iffy.

    EDM is out of the question. We don't have that capability here locally. I'm not having any luck with the carbide. Too brittle.
