I’ve always thought that the LEGO Technic Competition Cannon looked like the boiler for a steam engine.  I finally took the time to make it happen and this is the result.

There are quite a few friction based connections, but they are all pretty solid with the original version of the cannon. Unfortunately LEGO has since redesigned the mold for this piece, and although the connections still work, the main wheels are quite loose and there are some odd looking gaps in a couple of places.
