Hi,
I'm building a lego mechanism in which the gears experiences a high
amount of force.  I've split several 16-tooth gears, and I'm interested
replacing the standard lego gears with metal.  Has anyone heard of
somewhere I can purchase metal replacement gears?  Or alternatively has
someone done this themselves (not necessarily with metal) who could
help me out?
Thanks,
Jack

Re: metal lego gears


Maybe using multiple gears in parallel would help.

Re: metal lego gears

would be great to get lego bricks, axles,
and gears cast in aluminum or make them
from steel..  My first robot arm was lego
gripper, and I broke a few gears (they were
in "parallel"), and I took the gripper apart.

Re: metal lego gears


You could make some gears yourself out of "alumilite". I think it'd be
at least stronger than plastic.

I heard of it through the atlanta hobby robot club. (www.botlanta.org)
