This is an interesting thread. One thing that i have noticed is that ALMOST EVERY gearbox i have sene in first is grossly overly beefy. I have seen some beefier than some stages of my car's tranny. Last year we used metric module 1 (i think) gears with face widths varying btw 6mm and 8mm. They stood up just fine with no tooth chipping breaking etc. There was a very small about of wear and we may go to module 1.5 next year but they held up very well and we didn't have a single problem. Except for the final output shaft, all of our shafts were 10) REALLY hard steel (soo hard that is was difficult to machine. We actually shattered one of them during machining). We also used needle roller bearings.
