dorkpunch Engines- 2 cylinder Wobbler.

If you go back aways, you'll see the wobbler air engine I have my 8th grade students build in Metals 2.  Well, I've been working on another version of it.  Pretty simple really- just welded another valve plate on the opposite side, added another cylinder and piston, and cut the pistons so they can share the same crank pin.

Works okay, but still needs some tweaking.  Will run fairly slow but if I try and crank up the speed, it seems to be fighting itself and won't rev way out like the single cylinder version does.

Fun to play with, anyways!
