The 12-tooth bevel gears are not very strong to begin with. If your gears are
snapping then maybe you could try using the 12-tooth double bevel gears.

You can build a fairly strong housing for these gears by using 4 of this part
http://www.peeron.com/inv/parts/32056 to connect 3 of this part
http://www.peeron.com/inv/parts/32034 via 6 2-long axles.
Alternatively you can decrease the stress upon these gears whilst still
transmitting the same amount of power by having you're gearing down after your
bevel gears.
Hope this helps.
