 Started all over.

 Ground off all of the JB weld outside

 Ground off the JB weld inside around the bolt penetrations

 Drilled and tapped for 1/4-28

 Drilled sealplate for 1/4" bolts

 Wrapped sealplae in packing tape

 Alodined the aluminum using aluminum prep from auto body supplier
 It actually was a golden brown after the alodine was applied and rinsed

 Applied JB weld outside all around the SS tube in the area previously
 alodined.

 Applied vasoline to the threaded surfaces

 Mounted sealplate and torqued fasteners

 Wiped excess JB weld off of housing

 Let cure
 -----------------------------------------------

 Phase 2

 Removed 1/4" bolts and cleaned threads with lacquer thinner

 Removed sealplate

 Cleaned and alodined

 Cleaned threaded holes and cavities below with lacquer thinner

 Loaded the surface up with red RTV

 Installed new O ring in sealplate

 Mounted sealplate

 Coated threads on bolts with red RTV and installed

 Torqued bolts and cleaned off excess RTV


Phase 3

Coated edges of rotor housing with RTV and bolted test side plates on and
let cure over night

Immersed entire housing in water and pressurize with air 60psi +

It was necessary to install a C clamp in the middle as the 3/8" Al would not
hold a seal

It has been holding 60psi for a couple of hours.

Saw some small bubbles, not a stream, emerging from the tube to seal plate
which maybe trapped air occurring during assembly.

I will report any anomalies but as you can see here follow Pauls
directions to the letter to seal the P Port side plates

The immersion test is a great way to detect leaks.  I found that the leaks
can come from the test apparatus and side plates.

That includes using half inch thick side plates, inner tube
rubber  and ONLY C-clamps :)
