[PSUBS-MAILIST] Elementary hull

[hank pronk via Personal_Submersibles]

Greg,Elementary's hull is 1 inch thick and 48 inches ID  from 516-70 and pressed to meet ABS sphericity rules.  The hatch land is 2 inches thick and conical.   The sphere  is rated for 3,000 feet and tested to 2,800 feet at Nuytco.  I only went to 2,800 feet because that was the chamber limit.Hank
