Do you have a CAD or DXF file of your plate?  I do have Cosmos FEA

analysis

with Solidworks.  Please also indicate or drawo some more details about

the

spool mounts and I will see what I can do.

Marc Pedings

Thanks Marc. Here it is. We have not made the final decision on
the spool mounts. I think Jerry is still thinking about the casting.
This is to scale so you can dimension it off the ACAD R12 drawing.

This is what I have of the plate so far.  I need some more information so
that I can conduct a more accurate analysis.  I will be testing this
assembly with every environmental variable possible.  If I can get this info
from anyone, I would apreciate it.
Here is a list of a few questions that I have:

1.    Please give me the dimensions of the PSRU drive (SEE ATTACHED).  I
need this so that I can utilize cast aluminum for my frontal load analysis
on the plate.  I will attempt to simulate a dynamic environment.

2.    I need the length of the spacers/spools (from the engine to the back
of the plate).

3.    Since the quoted distance from the flange to the engine is 14.625, I
will be able to model a forged prop flange after I know the distance of the
spacer blocks/spools.

4.    What is the radius of the fillet within the pockets?  I assumed for my
model (attached below) a .1" radius.  This is paramount, for my initial
analysis has determined failure in this area.  I may increase this.

I will gladly publish any drawings and my findings after I complete the
analysis.

Tracy, can you help us out on these dimensions? Anybody? I don't have my PSRU
here. It is up at the hangar. 

Spacer blocks spools are 3.050 inches long.

Use a half inch ball end mill and it will give a .25 radius.
