Paul,
Latest update of the bellhousing.

You will notice the upper right and two lower ribs (stiffeners) contoured.

All

have draft (taper) front to back.

The three upper mounting positions have thickener blocks.

The engine mounting sides have square edges.

The 3 lower bolt positions have a drilled pilot hole.

The large circle is the flywheel - however with the draft (taper) the

position

isn't as critical at the edge, as what the photo

shows.

All mounting positions have the required shrinkage allowance.

Will check at the foundry that all is correct for their requirements before

ribs are stuck on permanently.

Internal ribs and stand-offs are not yet complete.

My personal assessment of the 4 o'clock starter mounting position is that

it

is too tight and I personally will settle for a

3.30 position. I will have to allow mounting blocks for the starter

positions

- do you still want to  try the 4 o'clock position

? It may require two sets of mounting blocks for the proto-type.

I've checked all the bolt co-ordinates and am working on the
starter location co-ordinates. All will be complete when it's time to

machine

the prototypes

How's it looking!?
George (down under)

Looking good. Starter position is not all that critcal. 3:30 or 4:00

Yep George, I agree with Paul...The Starter mounting position can go either
way, so go with what works best for YOU.....Just remember that the "Yankee
Export" model will have identical Left and Right Engine mounting pads, so a
little forward thinking/planning is prudent at this time ;)

Regarding your 8:00 o'clock Rib.....It appears that you're planning on wrapping
it around to the face of the Engine mounting pad??? If so, you don't need to,
since that corner is already very well structured (beefed-up) from the inside.
The same goes for the 9:00 o'clock Rib, just terminate it at the center of the
semi round built-up Engine mounting Bracket shoulder stop....(Mouthfull)
However, my observations could be wrong as it's very dark in that area of the
photo.

Other than that it looks "Cannon Proof"....You're practically ready to pour!!!
NICE, NICE JOB!!
