It looks as if both end housings were custom. Did he have external
oil
and water pumps?
Fred O.
I don't know. I would say probably.
Everett wrote an article on this engine for EAA Sport Aviation
mag. I would love to get a scanned copy of that article or just a
zerox if
possible.

Paul,
I mentioned this in the Deep Dark Past, Time Fastener Co. They do the
best insert for use in aluminum I have ever found. They were sold
through Kawasaki dealers in the '80s and might be still.
WWW.Timesert.com <http://www.Timesert.com> gets you there. These are
the best inserts ever made. The best part is that due to a unique timed
thread system they are no thicker than Heli-Coils, but the thread is
MUCH stronger. They make a range of metric and inch sizes. In an
aluminum end housing these will prevent pullout. As an engineering
upgrade to the regular threads they will greatly improve the threads.
As
a repair they produce a thread superior ot the original! I would also
consider a external oil pump and feed. For everybody's information.

Bill,
Timeserts win. Also, the front plate we are designing does not look
like a
Mazda part, as it has no intention of going in a car. Different oil
system,
water pump and accessory drives....

Larry, Bill Jepson is building a 3 rotor powered RV10 and lives in your
neck
of the
woods. Perhaps you guys can get together.
Also I have some experience designing casting patterns using
3D programs. I did some intake manifolds.
I would like to build this two piece end housing and try
out the idea. Similar to what Richard Sohn is doing. (Last four jpgs.)
I work with American International foundry in San Fernando. Would you
be
interested in hogging the pattern and core boxes out of aluminum? I
would
keep the
patterns simple by doing away with all side ports and a lot of the
front
cover stuff similar to the way Everett Hatch did it. I am sure we can
sell
a bunch of these things to the one rotor guys that have a severe weight
problem.

Where is bill out of? I am based in Santa Rosa area.
Larry
I think he is down in the Oakland or Berkly area.

Larry,
I work all over the S.F. Bay area. I've a rental in San Jose.
Mechanical engineering and design work. I also have a place in the gold
country near Jackson where I can be found most weekends. Our real home.
I've got my own Solidworks seat am I'm working on some designs for the
rotary. Send Paul a private message with contact info and I'll get in
touch off line.
