metal lego gears

Maybe using multiple gears in parallel would help.

You may want to pose this question to the Lugnet Site, its a Lego
related site: http://news.lugnet.com/robotics/

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.

Has some ideas on how to strengthen lego with metal and getting a very nice
result.

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)

    --Despite the allusion to strength in the name there isn't any
metal in Alumilite. OTOH it *is* really neat stuff: it's a 2-part
liquid that, when combined, sets into hard plastic in about 3 to 5
minutes. Generates a lot of heat while doing so, so don't make molds
from anything that's likely to melt or fall apart. It's very useful for
making small solid objects, but I've never tried to use it to make
things like gears with teeth. Well worth getting some, tho, just to do
the experiment; you'll think of a lot of uses for the stuff.
