Paul, I don't know if you have this covered in your  drawing,
but there is an oil seal of some kind pressed into the TC  PSRU
base plate. I'm shipping it out today to Jeff.
C.  Smith
Yes the oil seal counter bore on the back side of the plate  is
in the
3D I sent to Jeff.
Here it is in  Tracy's dwg.
Did you notice a shallow counter bore on the front  side?
I am not sure he is still shipping them this way.
What is not is the mounting holes for the starter. I found an error
in Tracy's dwg so I left out the holes. It is easy to match drill
the holes once you have the 2nd gen starter.
Jeff, please take some  pictures of the final product and send
them to
me.
I'll put your name in address in the parts for sale section  on
the web
site.
BTW we also need some one  inch OD spacers drilled and two of them
counter bored
for  the hollow dowel pins. That can easily be done on a manual
lathe.  Of course an NC lathe could knock out a bunch at low  cost.
Craig has a set of spacer blocks from Tracy's that are rather  crude
but the correct length can be determined by measuring  those.

I really don't  have any 3D of the plate..the cups came in.. Some
how  we
need to get that here....If I had that cutting will  start
today..............
The dowels are 16mm  or .6296, how deep you need them bored???.....
jeff
Did that that solid works file from Jarrett not work?
OK It appears  to be something wrong with the SLTPRT file extension.
Try  these.
I don't have an end housing here with the hollow dowels but  over
kill won't
hurt. My guess is 3/4 of an  inch.
Paul Lamar

I believe the issue may be that Jeff  is using an older version
of SolidWorks? I can save them as a  different file type if nesc.

Jarrett

Great Jarrett  please do that. I want to get this problem sorted
out for future  designs. Namely the two piece aluminum end housings
for those people  that have a problem with engine weight.
A certain percentage of  people show up attempting to install
a 13B in an airplane not  capable of accepting the weight.

The largest market of all would  be a one rotor engine that is not
now competitive with other 100 HP  engines on the market.

Thanks for all your help now and in the  past.

Paul Lamar

Here they are in  Parasolid.

No worries, I've got plans to do a rotary powered  unit at some point
as well so I'll get my payback then  :)

Jarrett

This file extension is news to  me.
I hope Jeff can import them.

Thanks again  Jarrett.

Paul Lamar



I think you need to  zip this file type, opens as text in e-mail.
C. Smith

Yes I already discovered that :)

I am new to that particular  file extension.

Paul Lamar

Paul


got the files  and have the material here...I have enough to make at
least 8 plates.I will  make 1 for inspection, then if you want more......

the pressure caps  can be done as well.. get the geom and advise  on
material....

jeff

OK do we have any other buyers? Speak up  now.

Paul Lamar


I would be interested if it works on a 20B, it will need to handle 300  hp

Stuart

The plate and cups will handle it fine. You will need to go up on
the Barry rubber bushing load ratings but they are available in a wide
range of loads. Use two -12 instead of two -11. We use the same series
as the Cont. 0-550 engine in the Questair Venture with a similar motor
mount design.
