Paul,  have  you had a chance to consider placing a single Barry
centered in hat section at rear of the engine?    I am still thinking
that the arms of the "X" brace could meet at  the weld bushing.   A way
to deal with  vertical  forces would be the issue.  Not  a problem for
TWs or conventional RVs because small tubes can be run from the top of
the gear receivers and welded in.  Also, not a problem for aircraft
with plywood fire walls, as a brace can be easily placed anywhere.  A
little more of a problem with sheet metal firewalls  but no more so
than what we are doing now.  In these latter cases the brace would have
to be bolted.

If this seems like a good  idea and passes the Rhino test,  I will
build a prototype immediately.

There may a joinery problem where the  tube from the outside Barry
joins with the  bushing at the lower corner of the firewall as the
angle between these two is very low.  Could you look at this when using
the 30" Schertz?     Thanks,   Jerry

I am not sure I follow you Jerry. Can you send me a sketch of what you have in mind.
Are you thinking of two rubber bushings at the rear.?
