The big problem with doing a bell housing casting is the pattern

have some parts with about that wall thickness.

Paul, could you do sections in the 3D machine and then assemble them?

I am looking into it.

Sorry, but I haven't been following this thread for a while.  How big is the
largest diameter on the bell housing?  The last time I looked at the
drawings, it looked like a relatively easy pattern to make: lots of
symmetry, and something that could be turned on a lathe pretty easily.  No
hand carving at all.  I need a good Christmas project!

Largest diameter is about 15 inches for the bolt flange.

Here is what I have come up with so far. The flat lower sides 
can be used to bolt on your fabricated rubber bushing brackets 
of choice. This give a maximum amount of flexibility as it 
seems nobody can agree on just how wide they want their rubber 
bushings to be. It is rather more complicate inside as various 
and assorted ribs are required to provide support for Tracy's 
PSRU. 

What does everybody think?
