Anybody ever made any of these? The pliers would be easy to make. The
drill jig is $475, the dimpling tools about $300 apiece, and the lockwasher
tool $100. Anybody ever make any of these, or are they patented? If they
are patented, maybe that explains the exorbitant prices.

I made and regularly use tools for installing dzus buttons and their
receptacles. I use them on my airplane. Does that make me a felon?
