They are two hemispheres, 1 inch thick. If these don't fit perfectly, I will just give a push with my porta power and brace. I am planning substantial bracing before I weld anyways. </span></div><div id="yui_3_16_0_1_1448813333276_2732" dir="ltr"><span>Hank</span></div><div id="yui_3_16_0_1_1448813333276_2732" dir="ltr"><span><br></span></div> <br><div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Sunday, November 29, 2015 7:59 AM, Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br></font></div> <br><br> <div class="y_msg_container"><div id="yiv5178992984"><div><div style="font-family:Arial, sans-serif;font-size:10pt;"><div>Hi Hank, I would definitely have substantial weld on there before cutting the holes, Are these two hemispheres?

I am planning to tack the heads together securely then cut the three port holes and hatch hole. I want to cut out the port holes witch have the circumference weld running through them before welding the heads together. I want the pieces from the port holes for test material. I want to weld them together to prove weld procedure and quality with coupon testing and I plan to stretch the coupons to breaking point also. I am not sure if I should cut all these holes before the heads are welded, it may cause the heads to distort. Maybe I should test with a 1 inch piece left over from the pod project. Hmmm thoughts anyone?</div><div dir="ltr">Hank </div></div></div>_______________________________________________
