. . . and today, a little solo display that I built, holding only four balls, ran for 2.5 hours at the Austin LUG meeting without dropping even one. WIN

Wow. I am embarrassed that my push arm-design is doing so poorly there. Aside from my excuses, if you replace the rubber washer and blue axle pin with a 7-hole liftarm and a black pin, you can do a better job controlling the swing problem that jams the arm.

And by all means, change the drive train! The side power shaft is not a feature for just one module.

I am pleased with more evidence that someone had fun with my design.

Passed that along to Will Heron, who built it. Thanks!
