Hi Sean,If a guy was to buy a 48inch id CNG sphere with a 4 inch shell thickness, would it be necessary to weld in a land ring and port seat.  Or could a guy or gal rough cut the necessary holes then put their  flange machine to work to machine seats in the shell.    It seems logical to me that could be done for the hatch because the load would be supported by the same steel in the hatch.  Or am I out to lunch?  Hank
