Or maybe Kan-Twist. We'll see.
I marked out some sheet yesterday and cut blanks today. For two clamps. Going to drill, pin together, and shape to final size as a stack for each leg. Probably tomorrow. Just waiting for the super glue to dry. At some point this stuff got really good (used to be terrible), but now takes 24 hours to fully cure. I never noticed the 24 hours part until I searched today...it didn't even say it on the package.
Anyway, I'm making small size clamps. The PDF I have contains an example spec'd drawing that's about 5" across the fully opened height. And I went with 2/3rds of that size.
I have no blocks of copper ($$) so I guess it'll be steel or element number 13 for the jaw pads. And the screw will probably be zinc plated if i can find it easily enough.
