You know, I have a stapler that I might try tomorrow with no staples. Just
press it down on the end of the nut, and perhaps it may have the right
amount of oomph to do just what I want it to do. The goal here is to
fracture around both ends so that the shell can be pulled off, but not
fracture so bad that it breaks up the meat inside.

Get a big solenoid and mount it on a board with a nut stop and bang away.

Push button pecan cracker.
