Hello!
> I'd never heard of an "onager" before
Onager: <gr.-lat.>: 1. half-donkey in South-West-Asia; 2. (hist.) Roman
throwing machine.
Says my dictionary. In German.
These Roman catapults were similar to my catapult. Well, I should say mine
is similar to their's :-)

Thanks for this explanation! I wasn't even aware of the term 'trebuchet'.
Maybe I should have searched after it in google instead of
http://dict.leo.org :-)

You are right, this catapult arm works well. But I don't like form parts
like this too much but try to find a 'real' LEGO solution.
