    6 Cyl Radial Air Eng (GrabCad)

    Thank you so much for the guys. So now I’m gonna go out and try to figure out how to make one of these rods a master rod. Should be interesting because they’re all meant to move right now. Again thanks a lot I will keep you informed

    6 Cyl Radial Air Eng (GrabCad)

    I am really confused now. Even when I turn it by hand the Conrad will sometimes bind up. Almost as if the center is not keeping up with the pistons. It can’t be timing because I am only turning it by hand.

    I had no idea. So you are saying in a radial one con rod is fixed? Thank you so much for that. I will try to fix one rod.

    6 Cyl Radial Air Eng (GrabCad)

    So I have spent many hours building all the parts and pieces for this six-cylinder engine. I put it together and I seem to have a problem with it. When I rotate it by hand the center wheel that holds all the conrods seems to fall behind in rotation to the crank shaft. What happens is the conrod...

    I was wondering. Has anyone ever built this engine from scratch without castings?

    I was wondering. Has anyone built this engine from scratch? Is it possible to buy the drw. By themselves. Maybe from someone who has built the engine already.

    It will not run.....

    Hey all. HAPPY DAYS!!!! I found my problem. When I first ran this engine I had no gaskets in it. I thought I will just see if it runs. It did. So I took it apart, painted it and put it back together ... with gaskets. I put a gasket under the copper wear plate that sits on top of the...

    It will not run.....

    Good question. I think because I have been flipping over the copper wear plate. Since I widened the Dvalve I am getting good air retention when the valve is in mid position

    It will not run.....

    You are right it almost covers. When I measure they are close to the same. But when I shine a light behind the slide valve I can see a sliver of light on both sides. I have made 2 new slide valves that give me .012” lap and I have made 2 new eccentrics at .125” the old ones were .098. I have...

    It will not run.....

    I I just added a short video to Media. If you look at it you see the slide valve open with air in the steam chest and then when I move the slide valve to the mid position you can still hear a lot of air escaping. The slide valve has lots of lube. Then you can see the engine run. The outer edges...
