Twin V CO2 Engine

[dennis]

I just finished building this engine. It was designed by David Kerzel http://www.john-tom.com/html/SteamPlans3.html. I made mine 2x scale from David's plans. I used stainless steel for the cylinders, brass for the pistons and connecting rods, drill rod for crankshaft, aluminum for the crankcase, flywheel, cylinder heads, etc. Brass and copper tubing for the intake. I also added a "porthole" so that one can view the action inside when the engine is running.

That looks really nice!
Maybe I'm dense - but where does it exhaust?

Thanks for the link to the plans, saving them for later. I like your idea of making it a little larger than the original.

The exhaust holes do not show up in the pics. They are located just below the fins on the cylinders, one on each cylinder. I made exhaust pipes out of copper tubing but I did not like how they looked.(too skinny) I have an idea for new ones so I will be back in the shop working on them.

Very nice job, a great looking engine. The john-tom site is a great resource. I'm working on Elmer Verburg's VR-75 from john-tom now.
