Last year we built our first gearbox. It was a 1000:1 reducer so the CIM motor could drive our box stacking arm. We started with 1/4" plate but then machined all the areas that were not holding bearings or spacers down to about 0.060". Of course, the CNC machines and software at our sponsor J & F Machine made it much easier. But it could have been done by hand on a conventional mill. You would have just had to be very careful. The weight reduction was substantial.

Thanks for making me do it Rick!
