Description: A short version of the previous long development video + new tests at the end. The target is to generate the maximum possible pressing force with Lego. The progress is measured using a disassembled person scale (max 180 kg). Enjoy! The long unedited version: youtube.com/watch?v=vl6gLxoT1vs p.s. Some of the gear ratios in the video are incorrect. Instead of 36:1 there should be 25:1. And 54:1 should be 45:1. Somehow I forgot that a middle sized bevel gear has 20 teeth, not 24.
