I want to make a steam engine that's compatable with my boilers (so I don't have to make new ones) and that uses actual pistons. This will be a multiple expansion steam engine (3-4 cylenders) and I found a good example on Wikipedia that should be possible on Powder Toy. But frame doesn't want to behave like that. The pistons will be easy but the valves keep getting destroyed. D:< Any solutions? (not portal)

P.S. Link:

look beside Multiple Expansion Engines

EDIT: here's a single cylender engine on I'm working on. But the piston gets destroyed before second stroke. -_-
