I hadn’t actually planned on building a second marble machine, but in March 2000 I had an idea for building a better marble elevating device, plus I had enough time on my hand to actually build a machine using this principle. And this is the machine I built… What inspired me to play with building a marble machine again was the idea for a marble elevating wheel, which would be very unlikely to jam.

    For your next geared project, look up “involute”. It’s not all that hard to rough one out, and your gears will likely last longer as well as run more smoothly.
