Slide your cable into that and snug the nut and it is done and clean looking. Also from my experience, I would not angle the wires, I would make it strait through and strip as much of the jacket as possible. I am sure your drawing is not representing the actual amount to be stripped, but it should be more significant. Keeping it strait will make it a lot easier, I have done over 20 wires in one penetrator with a strait threaded bore. </span></div><div dir="ltr" id="yiv1449724106yui_3_16_0_ym19_1_1494848739894_4816"><span>Hank</span></div> <div class="yiv1449724106qtdSeparateBR"><br clear="none"><br clear="none"></div><div class="yiv1449724106yahoo_quoted" style="display:block;"> <div style="font-family:Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:13px;"> <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, May 14, 2017 9:40 PM, Alan James via Personal_Submersibles <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br clear="none"></font></div> <br clear="none"><br clear="none"> <div class="yiv1449724106y_msg_container"><div id="yiv1449724106"><div><div style="color:#000;background-color:#fff;font-family:Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"><div id="yiv1449724106yui_3_16_0_ym19_1_1494815924300_2859"> Hi,</div><div dir="ltr" id="yiv1449724106yui_3_16_0_ym19_1_1494815924300_2858">I have a number of penetrators to do on my lights & other items, & I'm</div><div dir="ltr" id="yiv1449724106yui_3_16_0_ym19_1_1494815924300_3154">looking for the best materials for them.</div><div id="yiv1449724106yui_3_16_0_ym19_1_1494815924300_3076">My design is as below.
