Liquid Rocket Engine

My Rocket engine has been a continual quest since I was six years old. Granted, the Lego “Rocket Engine” I built back then didn’t exactly work, but I knew I would get It to work someday. Currently, my rocket engine runs on Isopropyl alcohol run through a fuel injector that I machined myself. There, it mixes with oxygen from welding canisters. The v2 assembly and v1 firing are pictured below. V1 produced a little over a pound of thrust. Hopefully, v2, once fully finished, will produce much more!
