Phil
Nuytten...Vance Bradley...can you respond regarding polished edges for
viewports?
I got the
info I needed back from the representative of Port Plastics. I talked to a
different representative than the one Scott talked to, and got
significantly higher pricing. I'm confident that the rep I talked to
understood exactly what I needed and in fact he returned to me the same
spec-sheet for R-Cast acrylic by Reynolds, that Scott received. R-Cast
acrylic by Reynolds meets or exceeds ASME PVHO-1 standards for
submersibles. Interestingly, Reynolds told Port Plastics that they would
not "certify" the material due to liability issues.

It's not
clear to me that a polished edge is a requirement. I thought I had read in
Stachiw's book that it was, but now I can't find the part of the book that I
think I read it in. Perhaps someone on the list has the answer and can
provide a reference? I think it's important to know.
This material
is not annealed after machining. Neither Port Plastics nor Reynolds
provides annealing services so this material would have to be annealed by the
home-builder (or sub-contracted out) to conform to ASME PVHO-1
standards.
