3-D drawings(some) of the parts:



Vid of it at full throttle(140p.s.i.):




no piston rings, each cylinder honed, as well as manifold, to slip fit, and runs on aquarium pump. Sorry but no drawings available.

That sure is fun to watch.

It looks like you've made some others. How many do you have right now?

Thank You for posting.
