Shop Tips has a plan for making add-on clamps. It directs that the end of a 3/8" threaded rod be "flattened" (to keep it from pulling through the end of a stripped T-nut in the clamping block). HOW do you flatten the tip of the rod to accomplish this?

The idea is to hammer on the end of the rod as if you were peaning over the head of a rivet. Obviously this must be done before seating the drilled-out T-nut in the block.
This is similar to the technique of hammering the end of a threaded rod or bolt to distort the threads so that a nut will bind. It's just more of the same since the nut in this case has had the threads drilled out. That just means that you need a pretty good mushroom head on the rod end.
