Were these much larger? Maybe these extra torques are due to contact forces
on the two bodies? Again, I don't know yet if this is necesary, we will have
to see what behaviors people come up with. It might just make it even a bit
more realistic.

OK sounds fair, I was just wondering about it :-)

 Anyway, I'll try to test universal joint since universal joint is used in

OK. you're doing great work! hopefully I can actually do some work soon
again too, instead of just talk ;-)
