Butch,
Would you recommend welding in a plate rather than leaving the end

open.

My thinking is eliminating possible flexing and optimising stress

transfer.

George

******Yes George, by all means, since the weight penalty is minimal

after

adding a couple of Inspection holes....However caution must be taken

upon

welding these plates on:

The preferred way is to cut the Casting, fit and weld the plates PRIOR

to

machining. If this becomes an ordeal to do:

Fitting and welding on the Plates to a machined Bellhousing can be

done,

providing the Bellhousing is properly bolted on a scraped engine rear

housing

that has a good, clean mounting face on it......This is a job for a

"PRO"

guys, somebody like Ed.......I personally wouldn't touch it with a

10ft pole,

even though I'm an above average welder (ARC, MIG, TIG and

Oxy-Acetylene).

BTW Pushers, you can cut an add'l 1" off on the R/H side of the

Bellhousing

if you want to make it narrower and lighter......(See attachment)

Butch

George, I think this is something like what Butch had in mind.
He is probably off in God know where doing what ever he does there.

BTW George I don't understand why you don't make your PSRU the
same out side dimensions and mounting bolt pattern as Tracy's. 
That would cut the cost of machining as both could use the same 
NC program. Here is a sketch of what Tracy's looks like with a 
few weight reduction suggestions on my part. After all you are 
using the same gear set as Tracy.

Also I think Butch's scheme for mounting the lower starter won't
work. The starter pinion is about 5 mm too far out to mesh with the 
ring gear. I would not start on the pattern until this is resolved.
