Topic tags/keywords: wooden toy spinning rubber band powered perpetual

Hi everyone; I don’t know here else to go to try to find this info. Google searches really do not turn up anything.

25 years ago or so, i built a few spinning toys (i called them “perpetual motion” toys) , and I’d like to build some more but I forgot part of the mechanism.

The toy has a 3/4” wooden base, and has two vertical dowels (usually ~1/4” diameter) about 8” tall. One of these dowels is simply a post for a string to wind around. The other dowel—at the other end of the base—has an additional dowel attached to it at the top horizontally, that spins, powered by a rubber band.

The small (usually 1/8” diam) dowel that spins has a string attached, about 7 or 8” long, with a wooden ball on the end. As the dowel spins, it slings the string and ball around. When the string contacts the dowel at the opposite end, the string wraps around the standing dowel, then unwraps. The tension of the rubber band then sends it around 360 degrees, and the wrap/unwrap process is repeated. This toy is one of those do-nothing toys, that is simply amusing to watch.

What i cannot remember is how the rubber band is attached to cause the horizontal dowel to spin.

Has anyone here made this toy, or knows where to find plans for it? Any help would be appreciated. Thanks,

Dan Blaylock

Try a video on youtube called Swing Thing. It shows one in action.
