i want to make a double piston steam engine to drive a toy car/truck/tank. how can i do that? Answered

Hi my name's Scott

I made steam boats with my father for the bath when i was younger(the simple syrup tin with holes, a candle and of course water.) and now since i taken time off from school i need something practical and educational to do. I wish to make a steam powered toy r/c car approx. size of xbox 360. I not going to worry about the r/c just yet. I've seen instructables on making steam powered toys but they were all ready made steam engines, i would much prefer to have satisfaction of being able to say i made most of that with the assistance of the more intelligent of my species here on instructables.

thanks

Start by looking up old model steam toy instructions.  ModernMechanic had one, VintagePlans, i think, had another.  The older plans (30's-60's) tended to be for home workshops, others assume a full metal shop and the ability to use ALL the tools :  (

Biggest problem I've seen is that most of the steam plans are 'set and forget'-they don't have any mechanical speed control, you adjust the fire and hope.

Seems like you could add an adjustable bleed valve and control the speed that way, though.

Waste a lot of power trying that ; )  Most controls adjust the amount of time that steam is allowed access to the piston-giving full pressure for a limited amount of time rather than less pressure for more time.

How much machine-shop experience do you have?

None. A friend of mine made a working metal cast of a k'nex V8 engine with old tins. Would it be possible like that? My dad is a member of the local woodturners association they have a metal shop in the some building.
