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.

Yikes George!!!!!!
You're moving faster than you're writing, I just finished answering your
previous x-mission......I guess you've been hanging around kangaroos too
long :-) Seems my reputation of "Speedy Gonzales" in the Industry is at
stake now :(
Like we've been saying all along, this sucker is going to be a VERY stiff &
strong BEAUTY, but unfortunately aquiring the penalty of weight, which can be
whittled off at the expense of machining etc., etc.
But more important, with the 1st POC physically in hand, you'll all of a
sudden see the roads to improvements and fine tuning.
I'm in agreement with Paul's suggestions, and feel that the center material
of the PSRU pad (Seal area) can be "Spoked in place".
I guess by the time this is published the machining will be completed ;)
Are you planning on test flying this weekend????????
