Not at all mate-I agree on your entirely as this was one of the solutions
I
came up with as well, simple and light.

However my concern with this approach was the attachment to the housing,
if
it were a separate piece.

As it is it can't be cast in, UNLESS it's made integral to the housing
(the
same as I made the internal reinforcement ribs in the prototype) and THEN
cut out with the starter snout hole. This then would leave more material
than your drawing depicts.

If it is a separate piece and not firmly attached to the housing - I can't
see how that would work?

As you can see I'm giving everything plenty of thought.

George, I believe we're both saying the same thing (Maybe)????

I'll iterate further:

PART OF CASTING---------It's do-able to cast this support in place as part of
the o/a Bellhousing, by casting the Standoff up to the Channel and machined
down to proper height in conjunction with Starter snout clearance hole
procedure/set-up....As far as the webs, they can be casted to a dead end
knife edge approx 50% higher, and filed/ground down to size....
Do you agree or am I missing something??

NOT PART OF CASTING-----This is what I originally had in mind to pick up the
mounting hole regardless of scenarios, but unfortunately the Starter's snout
penetrates much too deep and leaves no room, nada for the thickness of the
bolt head/plate....However it can still be employed if the Starter position
is not being utilized (same scenario as the cast in place)..See 195 Mtg hole-2

As you can see I too, have been giving this a lot of thought :)

Paul/Guys, I mislabeled the previous Bellhousing .jpg (270 Mtg.hole), it's
the 195 mtg hole......Please replace with attached 195 Mtg hole-1
