My first housing, intermediate center bearing support, 9.5 lbs when
finished.

Wow! That is a jewel Jeff. You do beautiful work.  Are you going to
 build
up an engine to test it?

  Jeff,

  Ditto Paul's comments on the beautiful work.  This is intended for a
 20B,
  correct?  I, for one, would be interested in one of these, after it has
  been
  shown to be airworthy, of course.  Maybe I'm not seeing it, but where's
  the
  oil pan flange?

The oil drain galley is not machined in yet and my version of this uses
dry sump......

 Jeff--second Mark's email regarding 20B.  Interested first in thick 20B
 housing.

 We machined aluminum 13B housing in the early 1990's with halves
 sealed with
 o-ring but never tested, opting at the time to proceed with aluminum
 castings. In process, as test hours accumulated, had to address
 cracks  in
 gear attach structure as well as around dowels.

 We can provide both dyno and flight testing of housings with both 13B and
 20B peripheral port engines with evaluation of structure and also
 alternate
 wear surfaces for comparison.

 If you proceed, we would like to obtain test housings prior to
 application
 of any wear surfaces.

This is an intermediate housing for a 2 rotor of my own
creation.........Certainly there  many similarities to the thick 20B
housing here. Is here a need for these??
I was considering the idea for a single rotor.
this is 2024 with lots of gusseting and filleting to minimize the
cracking issues you might see in a casting....I plan on continuing at a
constant pace, but as Paul can tell you this is a garage
operation.....With that being said, any assistance and experience shared
is always helpful..........

thanks

jeff

It is not your average garage :)
