Paul/Butch,
How's that !!?
A little heavier than anticipated -at 15lbs, however drilling and

milling should bring it down to 14lbs or less. I made the

stand-offs on the inside alittle larger in case I was off with my

measurements - but the shrinkage rate seems to be spot on.

What do you think - it is terribly strong!

Off to the machinist ASAP

Not to worry George. We can always cut some large holes in it with a hole

saw.

People want large inspection holes anyway and it will not hurt the

stiffness..

Now you know why I was calling for thin wall thickness.

I have some ideas for pocketing out around the input shaft seal area.
That can be done with a milling machine or the pattern could be modified.
Material inside the bolt circle of Tracy's PSRU adds nothing to the

strength.

I will know more when I see the actual casting. Can you ship it to me
after it is machined? Do you need some money for shipping or anything

else?

We are homing in on the final design. Maybe I will come down and spend
a week in your lovely city in a month or so.

Paul and Butch,
I agree about that centre (pad) section, it needs to be modified same way -
too much material.

I think I will get the initial CAD milling done, I will take the centre hole
specifications off Tracy's drawing  (I guess that hasn't changed?)

Give me a position for an inspection hole (or holes) size and I will include
them - don't worry if your not sure as yet, we can do it later.

I've decided I will modify the high side, a bit of 'cut and shut' and will
save some weight. I can be working on that while the housing is going over
to the US. No problem about money Paul, I'm happy to send it over for 'hands
on' assessment.

Your always welcome here Paul, can put you up as well, I have the room, it's
only a downstairs TV room but got a double fold out lounge /double bed - got
it's own shower and toilet, TV, computer, bar, it's quite comfortable.

Before I mill the sides,  I think Butch picked this up as well, I need to
know if the top MM hump has a square or concave cut. I'm concerned about a
stress area at the corner of a square cut.

I will send a separate photo of this area for Butch.
