Ron, Dave, thanks for the ideas. I slept on this last night, and decided to make yet another clamping system. I make them with parts I made from previous ones to save work and increase utility.
I have always been plagued with problems machining thin stock ans have been just too lazy to solve the problem. I think this new tooling will help. I used a 5" piece of 2" thick wall square tubing, squared it up, and made a hole pattern. The neat thing is I can always add more holes. I made a new edge clamp, but I can also use standard clamps from my other systems. Holes are 8-32.
It only took a couple of hours to make.
