Hi Paul;
       Attached are Wiggins assembly drawing and Wiggins
detail drawing in DXF format, which I checked and
imported into ACAD12 with no problem. It should be fine
in ACAD11.
I took the liberty of re-doing your drawing for
scrubbing purposes only and made some minor
modifications prior to ordering and releasing the POC.
The drawings have been already updated as per your
present request with the exception of the .050
bevel/chamfer on the sleeve. I made it .040 instead
otherwise we wind up with a chisel/sharp edge which is
not a good practice (will accelerate peening/foldover).
This will result in an .010 flat on each end of the
sleeve............What do you think?

Regarding the o-ring..............Paul as far as I know,
EPR seals/o-rings were originally developed specifically
to be used in conjuction with the very caustic synthetic
hydraulic oils such as SKYDROL and AEROSAFE since buna-n
breaks down in their presence. VITON seals on the other
hand was specifically developed for HIGH temperature
applications.
WHAT HAPPENED?

Looking forward to the Wiggins test results.
                                     Thanks
                                     Butch Diaz Sr.

I am just going on the chart in McMaster Carr Cat 105 page 2861
Viton is not good for hot water and steam. Viton rates "poor"
for that use.

Animal and vegetable oils are recommended for lubing EPR seals
I will soak one in Mobil 1 and see what happens.
