It’s a throwback this week to one of my favorite projects, but definitely one of the most challenging. This is a marble track with 1 inch diameter marbles. Most of the track is made with 1/4” and 1/8” thick Baltic Birch plywood. The big wheel has to spin about 3 1/2 times in order to lift a marble to the top. I’m pretty proud of that design.
