I have completed my first engine project, now I'm trying my first photo upload. Please bear with me.
This little guy has a 3/16" bore and 3/16" stroke. The flywheel is 5/8" diameter, crankshaft is 1/16" diameter drill rod. That is a dime in the first picture for comparison. The second picture shows it running on one of those cans of compressed gas used to clean computer keyboards. You can throttle it up and down with the trigger on the can. Sounds like a bumble bee. The design is by Elmer Verburg and is available for free download (.pdf) from www.john-tom.com . The plans are pretty good and come with notes on machining.
I'm currently working on Elmer's VR-75, a 3/4" bore and stroke marine style steam engine with stephenson reverse link. The plans for this one also came from john-tom. I'm going to try to do a better job documenting this one step by step.
