How did you end up making that sleeve? Is it machined out of one billet piece, a machined cast piece or a tube pressed into an oval shape and then machined or something?

No, no and no
It's cut with gas, (don't know what it's called in English..)
Then I have all machined the inside and outside in two setups.

Sorry if I missed this...but are you actually machining epitrochoidal inserts for your rotor housings?

Which I guess would mean you're also machining your own housings....?

Will you then need to create "port sleeves" that mount flush to the interior surface of the housing sleeve and extend into the housing itself?

I would think there would be major opportunities for leaks.

Very interested in your engineering approach for this.

You are totally bonkers! Should become a wicked rotor
Mass production in a few years to keep the "old" rotary scene alive?

You've never seen home-made peripheral port housings?
They all have to make sleeves

Are you going to use brass as a plain bearing?

No, it was just for the mockup. The shaft havn't been grinded on those surfaces yet. So the OEM bearing will not fit.

It rolls on! Have got so far that I could push the cage down from the boxes and start welding.
We have a total chaos in the garage right now, it use to be pretty crowded, but now it's extremely ...
We've only 100m2 to share

Started with one side, it took a terrible time because I was terrified to grind too much every time. Think I lift up that pipe in place hundreds of times.

Pipe number two took 10minuter
Suspect everyone is doing like this, but I simply took two paper and rolled around the ends of the finished tube. Templated by, measured the distance between the papers on the tube, and made ​​sure the seams were aligned with each other.
Then I took off the paper, and turned inside out on the next tube. Mirror: D
Again, it was I who was a coward, leaving a few millimeters on the first try, but then I put on like a glove!

Welding!
It was at the famous, that it was possible to bring down the cage when it is so tight everywhere.
Had to break away mounts to the dashboard.

Some stainless flanges for the exhaust done by a friend with waterjet/aquajet.
But they are about to get stuck in the CNC before they are done

Done with port matching and a little offset just to put the pipe into steady when welding.

Have used the CNC Lathe to turn my bushings to all wishbones today. Also has a movie on this, but it is so cruel big, so I have to do something there ...

Acetal (POM), also called Delrin, and stainless steel sleeve which is internally reamed to tight fit the bolts.
