As its name implies, this toy does nothing
but in a rather frantic manner!
Crank the handle and two pistons whiz merrily back and forth in their grooves
- almost but never quite colliding or falling out of the toy.
This project is well within the skill parameters of anyone who owns a router
and a dovetail bit.
