Hi Larry,
are you talking about bending bar stock for the tool tip holder ?
I would be careful if that is the case, it might change the properties of the metal and make it do odd and possibly dangerous things?
If you're talking about the handle then it's not so bad.
I made my tool tip holder from an old piece of garage door. The lifting arm, 50mm square and 12mm thick.
The height sure would be limiting if a 1/4" ball is all it can achieve! Hope you can remedy that one easily?
Just wanting all tools to be safe
Looks like your having fun designing it around your machine though
Ralph.
