Our man Richard Sohn came up with a big surprise
at this years Shady Bend Rotary Engine flyin.
I had the idea of using a steel plate and Royce (I think)
came up with the idea of just milling down the end housings
and using their wear surfaces.

There are a few details yet to be finalized but it
is 95% there. It uses a Subaru water pump so the
water pump location is flexible.

Richard did the entire thing on his CC (Cheap Chinese) mill :-)

Light weight aluminum end housing castings, detonation coated and

ground

are too expensive and too problematic. This is a cost breakthrough

and

a low technical risk, low tech solution.

As you may remember Richard successfully manufactures and sells

adapters

that feed 2 cycle oil to the apex oil metering pump from a separate

oil tank

instead of the engine having to burn that crud out of the oil pan.
Most of his customers are RX7 owners.

This will also work on a 13B and a 20b to further improve the

already

excellent power to weight ratio.

Sign me up,  Looks great, Just what the Dr. ordered.   If this is what
he can produce on a CCM, just think what he could make on a real CNC.
