I need an actuator, but one that is air powered preferably. Instead of the

The problem with a typical actuator is that the piston is small and the
air inlet is small. You can't get high speed actuation without high
pressure.
The nail gun has the accumulator built into the piston system with a huge
port between the accumulator and the huge cylinder. You can get high volume
for fast actuation plus a lot of force with less air pressure.
Gives you a lot finer control.

If I were gonna crack a nut, I'd make a hard rubber platform slightly
thinner than the nut. Drill a hole in it to guide the nut.
Then play whack-a-mole with a rubber hammer. Crack your nutz
and reduce tension at the same time.
