Bill, while I have you on the line we are in the R&D stage on the best
glue
to use for bonding the P-port tubes. What I have so far is RF-5407AS
Ceramic Filled Epoxy Potting System. Alumina filled.

Ever heard of it?

Curing agent is RF-9
Supposed to be good to 250 to 300 F. Pourable and room temp cure.

Specific gravity is 2.1
Color is off white.
Thermal conductivity (Cal)(cm)/(sec)(cm^2)(degree C) is 40 x 10^-4

Know anything about this stuff?

Main problem is it is $80 bucks a quart.
It also cost a bunch to ship as it is toxic.

Paul,  you might consider Duralco 4525 which is what I ended up  using.
  Good to 500 degrees and very tough.  Allow 24 hour for cure.   Jerry

Looks good Jerry. What did it cost you and where do I buy it?
