Here is the DFX Cad files of the engine, with dimensions etc. I put it inside a zip file - Happy Building

Thanks for the information and pics Boots!  The pictures show a lot more complexity than I originally thought, I can see where one could spend a lot of time getting the tolerances just right.  I originally thought the outer plates were stationary, but looks like they spin with the internal components.  If the outer collar is stationary, how do those outer plates contact the collar?

All of the components are Bolted together and the mass spins as one peace keyed to the drive shaft with in the outer lids. The pistons turn on their own shaft with in the block. It is fairly easy to balance and true. You mount the block and plates together with the keyed drive shaft in a lath with the drive shaft in the chuck. Then you true the outer plate on both sides - that's it. The most difficult part is cutting the pistons, I sent the job out and had it wire EMT cut because of the pistons tight radius. The rest is a peace of cake for a good machinist just a bunch of circles. I built the entire engine in my garage.

Merry Christmas, Boots-2b1

That is some really nice precision work done there. Can't wait to see it running.:cool::D:P

Ok, I got it now.  I had to look at the patent again, the outer lid with the main bearing isn't in the pictures.  So the collar and outer lid is stationary, and that main bearing keeps the internal mass away from the collar just barely, right?

I'm still interested in trying this out, I'm working on a variable resistance load bank and found a custom EFI kit that would work great with this.  I still would need to scale it down though, I'm not set up for V6 power.... let me know if you have a contact that could fab up a smaller one.

Yes you got it, the main bearing stabilizes the internal mass from slipping around. I posted the CAD drawings to scale in an earlier post. To scale down all you need to do is scale down the those drawings, they are dimensioned.

It is best to use a machinist in your area, someone you can talk to and stand over his shoulder a bit. Their is emachine on the net, they cut some parts for me a couple of years ago http://www.emachineshop.com/. They did a good job but were slow, it took about 6 weeks to get the parts. Make sure to give them all 3 dimensions and put the tolerances in the machinists notes.

I'm going to talk to a couple CNC guys about this and see what kind of price they can come up with.  Thanks for the tip on emachineshop! I've never heard of them, but with the free software and stuff, I could see myself using them for a lot of things in the future.  How are their prices?

Are you still around Boots-2b1? We are in a better position than we have ever been in, to look into your engine design again and possibly build one to run on a hydrogen setup of another members here on the forum.

Dayyum, I want one.
