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 id="yui_3_16_0_1_1448804235473_2410" dir="ltr">Hank </div></div></body></html>
