[PSUBS-MAILIST] Gamma bow dome

[James Frankland via Personal_Submersibles]

Do you need to go to all that trouble?  When I did mine, the reinforcing
ring was milled flat on the seating surface and I just pre-heated it and
welded it in.  It was so big I don't think there was any distortion and it
doesn't leak.

Just thinking of saving you what sounds like an expensive job.
