I certainly have no need for another old, lame magic trick like the snapper. I made the device so I could appreciate the lesson Roy Underhill provided when he made it on The Woodwright’s Shop.
The snapper could be made could be made by cutting the pieces first, drilling the hole, and then shaping it. You could drill the hole, shape it, and then cut the pieces. You could shape it, drill, and then cut. You could . . . as you see, Grasshopper, there are many wats to the tree. So, why do we do it the way we do it? We drill the hole first, shape it, and then cut the individual pieces because it is easier to work the wood as one unit. The lesson is in order of operations: leave it long, trim to fit.
The individual pieces were then cut. The body is 3″ long and the snapping end is 1″ long.
A small plug for the bottom of the body was cut from the dowel rod. It is glued in place with a rubber band. As the rubber band does not actually do any thing, there is no particular method needed to secure the rubber band in place. I simply shoved it in with the plug and glued it all with wood glue.
Notch the dowel rod to make the hook. Like the rubber band, the hook serves no purpose. It does need to look like it could hook the rubber band though to sell the trick. The hook is then glued in place. Once it is dry, the dowel is cut flush with the head.
To use the snapper, squeeze the chamfered ends to shoot the end into the body. To make this entertaining you need to act like there is some skill and dexterity needed to hook the rubber band. Also, to make this entertaining, it helps if your audience consists of your young nieces and nephews.
