  • steam engine model attemp

    this is something ive wanted to do for a while . ive mastered ever kind of aririfle on the planet and thats my main hobby , but figured id try this ....and figured id post it for who ever gets the same stupid idea to build a model steam engine

    my idea for this is all out of my head so i'm not betting it will be 100%successful , but im hoping to use a valve style from one of my air rifles to drive the piston .pictures when its done

    so far my wheels and push arm and cam are looking good , (i think). some simple hand gcode for the wheels and arm shape .2 wheels are just over 6'' , 1/2 round rod for straight through rod and .4round for the cam which is off set for almost 1 '' travel.

        Like it or not JEZX, you're now in charge of all flywheel designing/machining.

          Just think about the catapaults on aircraft carriers. They can launch a 40,000 pound aircraft from zero to about 160 with no hand on the stick. Course they use superheated steam at about 900 degrees and about 1200psi pressure. Frank

            It's my own opinion but I think your going to need more rim weight , you need the inertia to keep it going.

              is that for a double action or single ? i could always put an extra steel rim on if i was to go with single action but
              ive been messing with the double action valve idea which id think would run it easily
              as ive never built one and it is going to be different then any other out there im sure i will learn a few things ....i'll probably learn that i should have built it like the designs known to work over the last few hundred years
