That's Chuck's Solid-Steel-Prop-O-DeathTM ;D ;D Nobody was willing to try and stop it at the demo.metalmad said:HI Chuck
is that a fabricated display prop ?with no pitch?
looks a bit like aluminum from the pics ( I don't Trust my eyes even with my new glasses lol)
Yes, it's a rotary valve. The air coming in the back of the engine is fed into the hollow camshaft. As the camshaft turns, the air is directed through one of 4 holes in the side of the cam into the curved brass tubes leading to the cylinder heads. There is a spring loaded ball bearing in the head that is normally pressed up against inlet port and allows (exhaust) air from the cylinder to exit through the exhaust port on the underneath side of the head.compspecial said:Its a beauty, chuck, and sounds almost full-size I love the 4blade metal prop too!
but how does the inlet system work? is it a rotary valve?
