I like to bolt the wires on but I see in your case that may be tricky with the ID of the hose being in the way. I thread the fitting all the way to the shoulder to increase surface area for the epoxy. I have not solderd wires on, I make my own crimps and shrink tube if I am not bolting. That is because as a rule my thrusters are meant to be jettisoning, at least on Elementary. Gamma has the escape pod so I am not as worried. Also James makes the best point, epoxy can NOT handle heat AT all. You might be able to bolt your wires on if your three penetrating rods are different lengths. This way the connections are not in the same spot inside the hose, maybe? It is pretty easy to make crimps, I just take a rod and drill the size to match the wire and the rod and slip on and crush.</div><div id="yui_3_16_0_ym19_1_1485190634871_7069" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1485190634871_7069" dir="ltr">Hank</div> <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 Monday, January 23, 2017 9:44 AM, James Frankland via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br></font></div> <br><br> <div class="y_msg_container"><div id="yiv0859400647"><div><div dir="ltr"><div>Brian. I would suggest threading for the reason Hank says, but also so you can screw on the wire connections with nuts and washers. Soldering onto those thick copper rods is difficult and if you've potted them first, you risk breaking out the epoxy with the heat. Or solder the wires to the rods before potting. I didn't of course and had to break the whole lot out and start again. In fact I think I must have made almost everything on my sub twice. :)</div><div> </div><div> </div></div><div class="yiv0859400647gmail_extra"><br clear="none"><div class="yiv0859400647gmail_quote">On 23 January 2017 at 15:53, Brian Cox via Personal_Submersibles <span dir="ltr"><<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>></span> wrote:<br clear="none"><blockquote class="yiv0859400647gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div class="yiv0859400647yqt7319138659" id="yiv0859400647yqt94024"><div style="font-family:Arial, sans-serif;font-size:10pt;"><div>Hank, Do you put a proper thread through the entire length or just a cut that is not intended to have a threaded bolt go thru ?</div><div><div class="yiv0859400647h5"><div> </div><div>Brian<br clear="none"><br clear="none">--- <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"><br clear="none">From: hank pronk 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>><br clear="none">To: Personal Submersibles General Discussion <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs. org</a>><br clear="none">Subject: Re: [PSUBS-MAILIST] elec thru hulls<br clear="none">Date: Mon, 23 Jan 2017 15:20:35 +0000 (UTC)<br clear="none"><br clear="none"></div><div style="color:rgb(0,0,0);font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px;background-color:rgb(255,255,255);"><div><span>Brian,</span></div><div dir="ltr"><span>Those look very nice, and you will enjoy filling them with epoxy with such a big throat.
