Each gearbox is built from scratch and then tested for speed and torque. Flat layouts only (gears are on the same plane) for better visualization. Enjoy! 00:00 2-speed 01:09 2-speed with driving ring 02:31 4-speed 04:02 6-speed 05:58 8-speed with WATCH VIDEO
Wanted to make a long gear train where all the gears visibly rotate. Using only Lego parts. Restriction: the first gear and the last gear must rotate at the same speed (gear ratio = 1:1). Enjoy! Music: WATCH VIDEO
Let’s see how Lego-compatible aluminum beam deforms or breaks when high torque is applied. The test bench is made using only plastic Lego parts (and string). Enjoy! The beam dimensions are the same as WATCH VIDEO
