Pellet sorting idea

"John_in_Ma"I doubt he is sizing the skirts, just the head. It looks like the two top plates are spaced up from the plate the skirt sits on allowing just the head to get "pinched".
Well that makes sense, I guess heads can't get out of round. ;)

Seriously though, I think you are right because the angle brackets are bent, not extruded. That would leave a small bevel at the base plate where the skirt would slide freely. It is a good idea.
