<div dir="ltr"><div>I would solder on any connections before assembly. Or make sure you have some method of attaching the wires to the threaded rods. Bolts, whatever. Its impossible to solder to the rods when they are potted\delrin's in place without damaging the delrin or potting compound. you just cant get it hot enough. I didn't, and its caused me 2x motor rebuilds due to connections coming lose.</div><div>regards</div><div>James</div><div> </div></div><div class="gmail_extra"><br><div class="gmail_quote">On 7 February 2016 at 21:27, Hugh Fulton 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 lang="EN-US" vlink="purple" link="blue"><div><p class="MsoNormal"><span style="color:rgb(31,73,125);font-family:"Calibri","sans-serif";font-size:11pt">I seem to remember that Rule of thumb is 2000 amps / square inch for copper so 50 amps would be 3/16” diameter.<u></u><u></u></span></p><p class="MsoNormal"><span style="color:rgb(31,73,125);font-family:"Calibri","sans-serif";font-size:11pt">¼” diameter would be OK for 100 amps.

You could solder the wires to the end of the rods or crimp. Then encapsulate the connections, I assume that is what your thinking with that void at the top. The beauty of your material choice is you can get more rods into one penetrator. <u></u><u></u></span></p></div><div><p class="MsoNormal" style="background:white"><span style="color:black;font-family:"Helvetica","sans-serif";font-size:9pt">Hank<u></u><u></u></span></p></div><div><p class="MsoNormal" style="background:white;margin-bottom:12pt"><span style="color:black;font-family:"Helvetica","sans-serif";font-size:9pt"><u></u> <u></u></span></p></div><div><div><div><div><p class="MsoNormal" style="background:white"><span style="color:black;font-family:"Arial","sans-serif";font-size:10pt">On Sunday, February 7, 2016 9:41 AM, Jon Wallace via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>> wrote:</span><span style="color:black;font-family:"Helvetica","sans-serif""><u></u><u></u></span></p></div><p class="MsoNormal" style="background:white;margin-bottom:12pt"><span style="color:black;font-family:"Helvetica","sans-serif""><u></u> <u></u></span></p><div><div><div><div><p class="MsoNormal" style="background:white;margin-bottom:12pt"><span style="color:black;font-family:"Helvetica","sans-serif""><br>Hank, I need penetrators for 36vdc power to motors (50amp), 12vdc power to lights (20amp), and other small electronic sensors.
