I have been somewhat following the discussion about the mount plate for the reduction unit.
may I suggest another way of doing it.
I have a mazda bell housing in my hanger which looks about the same depth of offset from the engine to the reduction housing. it already has the mounting for the starter motor. There is a large
hole in the transmission end  with bolt holes around the hole.
It would not be difficult to make an adapter plate which centers in the hole in the bell housing and also centers the reduction unit.
This part would be easy to machine on a lathe without any special tools. Offset could be adjusted in or out as necessary by
making the adapter plate into a cup shape if necessary. If any of
the builders have a 12 to 14 inch lathe many of these could be produced quickly.

Engine mounts could come off the engine or reduction unit end of the bell housing via 4130 tubing. These could be made in any
home shop with just a gas welding setup. The mount could even be triangulated back to a bolt hole on the block to transmit thrust
loads. I have done a similar mount in my shop with just a hacksaw,grinder and gas welder. Even the cups for the rubber
isolators could be made from tubing and sheet. This is even aircraft quality if done carefully. Perhaps the builders could pool
their skills and tools and make multiple pieces for all.

Good idea.

C.J., tell us more about your rotary powered Rutan Defiant airplane. Has it flown? Where do 
you live? Perhaps I could pop over and go for a ride :-) Take some more pictures too.
