<DIV class=y_msg_container><BR>It was an engineer hired by the company that commissioned and purchased the 600. His calculation requirements for the heads came out a little bit thicker than what George had calculated. I believe George spec'd .5 inch and the company's engineer spec'd .5625 inch.<BR><BR>--------------------------------------------<BR>On Thu, 10/24/13, greg cottrell <<A href="mailto:jgcottrell2002@yahoo.com" ymailto="mailto:jgcottrell2002@yahoo.com">jgcottrell2002@yahoo.com</A>> wrote:<BR><BR>Subject: Re: [PSUBS-MAILIST] K-600<BR>To: "Personal Submersibles General Discussion" <<A href="mailto:personal_submersibles@psubs.org" ymailto="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>><BR>Date: Thursday, October 24, 2013, 9:25 AM<BR><BR>George attributed the miscalculation in the weight<BR>of the 600 to second guessing the thickness of the heads.<BR>His original design called
