| My brother built a ram jet engine in high school. It was the same design as the V1 rockets had in WW2. That was 22 years ago. There was no CNC back then, at least not 5-axis. He also built a 6 cylinder steam engine that only had 5 moving parts. He built that when he was 15 years old! Any guesses how you could have 6 cylinders and only 5 moving parts? Dan |

| Hi Toymaker, Very close. The 3 double ended pistons were 90°, not V shaped. It worked very well. I believe it was called an Elbow Engine. It was on display in the high school machine shop for years after that. Dan |

| I played around last year bulding stuff out of metal for the first time. I found It very enjoyable. The first little engine I built was a single acting wobbler steam engine. I made the body out of clear machinable plastic so you could see the moving parts. (or part so to say-piston)

| the secret to this is making good valves, they have to be a fairly light sheet metal and have a good seal. All of the ones I have done are the steriotypical slot style valves like on the V-1 engines, but I have toyed with the idea of using cocentric discs as valve elements (as on the classic "red head" style modle engines). The most effective way of forming a seal in my experience is to use thin (.05") strips of gasket material (the mannila looking stuff) attached to the contact edges of your valves (I use epoxy, surprisingly it wont burn off unless you abuse it) this creates a tight seal when in opperation. For the exaust duct dimensions i just take some old drawings for engines from text books and scale them to what ever size I want.

I'm not ready for turbine engine..but how about a jet drive pump. Complete from head to toe casted parts. I'll post some pics in here when I get the pix. .. funny thing is though, it is too heavy to put into the r/c boat. I believe it weights over 6lbs
