Review on 🎢 ROKR Mechanical Puzzles Waterwheel Coaster: The Ultimate DIY Puzzle Challenge! by Michael Bressler

Ball size or smaller than pictured! This means that there are two people going up each step. While this doesn't result in a stop, just think that it makes it seem like it's not working properly. Spent about 4 hours straight. Some of the errors I found are due to my not interpreting the charts. The biggest thing was the assembly of the large drive, lifting wheel, parts 23,24 are swapped. Removing it from the finished assembly required a bit of skill. He removed the shaft, lifted it up and dropped the washers. The replacement in position over the shaft, added a dab of superglue to the edge of the washer to keep the holes aligned, placed it back in the machine, then carefully reseat the shaft. It works now. The symptom was that the balls would not come out of the gear, which was biased inward rather than outward. It turned out that the easiest way is to specify the details required for each step. A small node I used to place notes to mark "L, M, N, O, P, Q. etc." so they're easy to find when creating a track.
