I am so encouraged about the ability of my foundry to cast
thin sections I decided to design a cast bell housing.
Anybody interested in a combination bell housing and
motor mount. One advantage is the mounts are moved back
a couple of inches to get them closer to the engine/psru/prop
CG.

Tom are you interested in doing the pattern?
The cost over a motor plate would probably be near a wash.
The material alone for a motor plate runs about $100.
Then there are those long 10 mm bolts that Tracy supplies
as well as the 1/2 inch plate spacers. Tracy could sell this thing
so perhaps he could make it optional.

  Nice piece of work Paul. But the 31" width eliminates it from
consideration for anyone building "skinny" airplanes like my RV-4.

Mike Wills

True Mike but the economics of casting demands that we go for the 
largest market possible. Most airplanes are side by side and even some
of the late tandem RVs have the wide firewall and cowl. You could 
always cut off the ears and come up with some other means of mounting 
the motor mounts. The wide mounts gives plenty of room
for turbo's and muffler's.
