Moving On/Moving Forward, means: ......I will not let this very Important
and
Beneficial project to all, be buried again for the second time, so I'm
getting involved in the hard-core design aspects of it. I will soon be
submitting a layout which will consist of ideas and suggestions which have
already been contributed by all of us plus a few new ones, together with
my
personal pondering on the subject which should please everybody a sort of
WIN, WIN situation for all......So stay tuned......Just give me a few
days to
suck up some sea level air as I've just arrived from being on top of a
very
high mountain in a classified location for almost 2 weeks 8(

Hi Gang;
Per my above posting on September 27th, I must apologize for my tardiness
but
unfortunately it was due to two very good reasons, #2 first...I had to go
back up to the Top of the mountain, (No Paul, not for inspiration but to
work
my butt off on something unrelated) :( ..#1 which took the longest, I did
not
realize this undertaking was going to be such a Pain in the A-S. 8-(
But the great news is that I was able to gather and throw all the valid
suggestions from Paul, George and ACRE into a pot, added a few new ones
of my
own together with some spicy ideas and voila, came up with a pretty
good "Sancocho" (Stew)......The best part is that everybody here can WIN,
if
they want to of course.
The attached .gifs show the dimensions in mm, so for the benefit of those
who
are metric system challenged, just multiply by .03937 in order to change
it
to the NUMERO UNO system in the world, (No fighting please) ;) BTW, I've
always charged 15% more for Metric projects....Are you listening Georgie?
:-)
-The Front-Side views shown, is typical for both Tracy's RD and George's
PSRU...Shown is Tracy's Starter model mounting holes according to his L/O
drawing, at 8:30 and 3:15 positions since it seems to be the acceptable
norm,
but I'm sure there are a lot of others out there that can be accomodated
as
well if not better...The hidden red line on the bottom represents the Oil
Pan's sealing surface for the 13B...Views depict projection of 3 deg draft
angle from the nose down to the Flange's outer diameter, (The reason why
some
of the lines appear to be doubled or wavy)...Bellhousing to Engine
mounting
holes (5 pls) will require light Spot Facing to clean the Bolt area and to
remove most of the corner radius off the 7:00 oclock position
hole......The
sixth hole located (of all places), right smack in the center of the 8:30
Starter position, is not really necessary for our purposes, however for
the
sake of the Belt and Suspender individuals out there, I have a solution
(More
on this later)...The Tripod pads are there for the benefit of George's
PSRU,
which will be used on aerobatic a/c. For those of you who won't need them
or
are hard-up for weight savings, they can be Die Grinder removed with no
problem at all, or they can be used as mounting Bosses or for WYW..(FYI
Paul,
they make great Tooling holes for machining) ;)
The beauty of this Bellhousing is that it can be used with both Tracy's RD
and George's PSRU.....They only differ on the rear vs front machining of
the
Psru's mounting nest (Under-cut), see Xsection views.
The RD PSRU Xsection view shows the minor conversion necessary to adapt
Tracy's RD to the Bellhousing without Tracy's WARRANTY being
jeopardized...The mounting flange (Purple), is actually rough Bandsawed
out
of the ORIGINAL RD mounting plate and the OD is Lathe turned to fit, then
the
outer mounting holes are L/O'd and drilled. That's it!!!
I'm going to stop right here and give you guys a chance to take all this
in,
as I've been living with this for a month.
As always I encourage all of you, especially the Lurkers, to speak your
piece
on this regardless that you won't be buying or using one, or even if you
may
think your suggestions/comments are stupid/silly....As I don't believe
Silence is Golden.
GUYS, I'm looking forward to your responses.
Thanks,
Butch
