Default Re: Something new and kinda sorta 100 years old looking

Second try today. Hopefully third time is the charm because this ain't it. It just doesn't want to spin past top dead center. These slam valve motors are supposed to work even though the steam starts coming in before top dead center (a simple pushrod lifts the ball in a check valve as the piston comes up and over). I think the deal is the slight delay of incoming steam is overcome by the inertia of the piston. But it ain't quite right yet. I'll partially disassemble this thing again and improve on the steam flow by grooving the tappet I use as a valve actuator and see if that works. If not, I have a plan "B". Oh, it does make steam just fine:
