Why aluminum and not steel? I'm always a fan of saving weight (aren't we all) but I like to keep a bit of "beef" in areas prone to failure, or where I have seen failure before.

I don't know enough to do the calculations, but if someone can mathematically convince me that aluminum 20P gears are suitable in a FIRST robot gearbox application (even say non-shifting), then I'll run right out and by some.

But, because I can't mathematically prove or disprove the success of aluminum gears, I always just opt for the safer side and go with steel, as do most teams I assume.

If someone has done an aluminum geartrain and it worked, I'd love to hear about it and see some pictures. If anyone thinks it will work, I'd love to see some calculations. I'm not by any means saying it does or will not work, I am saying I have no clue and would really like to find out.
