<div dir="ltr">Hank, My forward port (16") was about 3/16" too large in diameter because the machinist that made the receiver machined it wrong and I didn't catch it until it was already welded into the front elliptical head. and so I didn't want to cut it out and have it widened that much.<div>I am still waiting to hear back from an annealing company after sending them the data sheet that I received from Sean and Cliff. </div><div><br></div><div>Rick</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sat, Feb 8, 2025 at 10:49 AM hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:13px"><div dir="ltr">Rick, </div><div dir="ltr">I just welded my forward port frame into my new diesel sub and it warped .008 inches. I decided the easiest way to fix this was to cut out the head 4 inches bigger that the port frame (20 inches) I took the assembly back to my lathe and machined it true. Now I will simply weld the section back into the head and its all done. A days work. I am mentioning this as an option for you to avoid annealing your port. </div><div dir="ltr">Hank</div></div></div>_______________________________________________<br>
