Hank, My forward port (16") was about 3/16" too large in diameter because
the machinist that made the receiver machined it wrong and I didn't catch
it until it was already welded into the front elliptical head. and so I
didn't want to cut it out and have it widened that much.
I am still waiting to hear back from an annealing company after sending
them the data sheet that I received from Sean and Cliff.
