Sounds like a good idea, but I seriously doubt if a HF bolt cutter is strong enough to do that swagging. I bought a set to cut 3/8" rebar. The handles are so springy, it is difficult to get enough force to cut. After struggling to get through 3 or 4 cuts, the blades had big gouges and would no longer cut. I realize you are probably going to make your own swagging dies. Just saying the basic tool itself is not really very strong. Of course there is the warranty, they took them back with no problem.

Be sure to save your receipt!!!!
