To keep it simple, I would like to do two o-rings on the bore with an over size end to create a shoulder and then a snap ring to retain it. You would get the penetrator with a hole or holes bored through and three grooves, two for o-rings and one for the snap ring. All you will have to do is cut the rod to length and thread it in with some epoxy on the threads. </span></div><div dir="ltr" id="yiv1679475759yui_3_16_0_1_1455035750201_4205"><span>Hank</span></div> <div class="yiv1679475759qtdSeparateBR" id="yiv1679475759yui_3_16_0_1_1455044579199_22266"><br clear="none"><br clear="none"></div><div class="yiv1679475759yahoo_quoted" id="yiv1679475759yui_3_16_0_1_1455044579199_22270" style="display:block;"> <div id="yiv1679475759yui_3_16_0_1_1455044579199_22269" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px;"> <div id="yiv1679475759yui_3_16_0_1_1455044579199_22268" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"> <div class="yiv1679475759yqt4665306230" id="yiv1679475759yqt60377"><div dir="ltr"><font size="2" face="Arial"> On Tuesday, February 9, 2016 8:52 AM, Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br clear="none"></font></div> <br clear="none"><br clear="none"> <div class="yiv1679475759y_msg_container" id="yiv1679475759yui_3_16_0_1_1455044579199_22275"><div id="yiv1679475759"><div id="yiv1679475759yui_3_16_0_1_1455044579199_22274"><div id="yiv1679475759yui_3_16_0_1_1455044579199_22273" style="font-family:Arial, sans-serif;font-size:10pt;"><div id="yiv1679475759yui_3_16_0_1_1455044579199_22272">Hank, so to clarify on the Delrin, a copper threaded rod ( 1/4" for instance) would get threaded into the Delrin?
