<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="gmail_extra"><br><div class="gmail_quote">On 23 January 2017 at 15:53, Brian Cox via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><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="h5"><div> </div><div>Brian<br><br>--- <a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a> wrote:<br><br>From: hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a>><br>To: Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a>><br>Subject: Re: [PSUBS-MAILIST] elec thru hulls<br>Date: Mon, 23 Jan 2017 15:20:35 +0000 (UTC)<br><br></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.
