Let's see how Lego-compatible stainless steel axle deforms or breaks when high torque is applied.
The test bench is made using only plastic Lego parts. Enjoy!

it was later sold by cncgear on EBay (obsolete) https://www.ebay.com/itm/19-units-long-stainless-steel-axle-X-style-works-with-Lego-Technic-gears/262583950400
