I was really happy with my original Desktop Pendulum Wave Toy except that it doesn't take long before the pendula stop moving and you need to restart it.
To fix this, I added grease to the insider of the bearings, which made performance worse.
When adding a lubricant to a model makes it worse, it's time to go back to the drawing board…
This new design changes the pendulum / support bar interface so that the pendula rock back and forth on a fulcrum, which should minimize frictional losses.
What's Missing
- The frame pieces are unchanged, so are not reposted – go to my original Desktop Pendulum Wave Toy to get them
- The new design no longer needs bottom spacers
Assembly
To get the pendula onto the support bar, place the point of the fulcrum over the edge of the slot and push. It takes a minute to get the hang of it.
