What's up engineers?! I'm not an engineer. I'm a pilot. But I've got an idea for an invention that requires a small gearbox. I have no clue where to begin, but thought that I could possibly teach myself how to design and build a small gearbox. Is there like a gearbox for dummies book or something? Seriously though, if you could recommend some basic books that could get me started I would greatly appreciate it. Thanks!
