Paul,
(feel free to publish the updated file I sent you recently)
Bell housing updates are complete and I will be cutting the new pattern
during the holidays. There will be 2 versions to fit the 2 different gear
ratio's. The new design includes everything we learned doing the first batch
and is a big improvement. I will have half dozen of the originals for anyone
interested, but we will have to coordinate as there are differences in
Tracy's gear boxes that we have to pay attention to.
And yes, been buried in work.... starting to free up and get back on rotary
stuff.
Larry

What about retrofits Larry? How does one go about
adapting their existing boxes?

Paul Lamar ...No rotor no motor.

Paul,
Is that your drawing or Larry's?
I notice a significant reduction in rear flange height, I notice when Mazda
reduces height of the rear flange, they increases thickness.

I notice the nice design separation of the starter motor mount. This looks
nice but might make the sand cast harder getting sand in all those corners
(without flaws).

I really like the front stand-off, do you require it that deep? I guess it's
replacing the rear part of Tracy's PSRU - if so nice concept!

Overall very nice indeed.

That is totally Larry's concept.

Paul Lamar ...No rotor no motor.

Paul and Larry,
As I suspected - what is the large missing side section?
George (down under)

George,
The side section is where there is no mounting position on the housing and
allows inspection of Tracy's flywheel mounted isolation bushings. FEA showed
no negligible loss in strength with this cut as long as the large corner
radius is left in.  Saves weight as well.
