I'd like to build an end of bench vise and what's in my head would use those quick release c-clamp style screw mechanisms. I'm tempted to cut some c-clamps up but what's left over will not be easy to mount. Any one have any thoughts on a different piece of hardware to "borrow" from for this? Basically I'd like to have a flange mountable nut (of size comparable to a c-clamp or bigger) that has a quick release button for quickly sliding a screw through. Any suggestions?
