Attatched to it is a dc dimmer, and a duplex outlet at 12v.<div>My cutting rigs consist of a bow made from 1" pvc with sweeps vs short 90 coupler. I ran an extension chord thru the bow to each end with an internal knot at the exit point. On each end is a eyebolt with an internal nut, washer, wire, washer, and nylock nut. The nicrome wire is pulled taught, and wrapped thru the eye bolt. The bow dimensions is 12 x 40. The power supply provides enough power for the nicrome. It cuts at about 12" per minute. This rate gives a pretty smooth finish. The second rig is a pair of pvc pipes about 16" long. Any shorter without the dimmer, is two hot and cuts to fast. Your arms are the tension, but lots of flexibility.</div><div>David</div></div><div class="yiv2989607409gmail_extra"><br clear="none"><div class="yiv2989607409gmail_quote">On Feb 23, 2019 9:45 PM, "T Novak 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"><blockquote class="yiv2989607409quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div class="yiv2989607409yqt9447017057" id="yiv2989607409yqt93816"><div lang="EN-CA"><div class="yiv2989607409m_-5407276774397796605WordSection1"><p class="yiv2989607409MsoNormal"><span style="font-size:11.0pt;">Hey David,<u></u><u></u></span></p><p class="yiv2989607409MsoNormal"><span style="font-size:11.0pt;">Please show us a photo of your hot wire foam cutting rig.

Built my first hot wire rig and cut the first piece of foam. The hot wire rig built from a recylcled transformer from an old computer and pvc pipe. It works pretty well, but discovered that i need to make a few modificatations to wire connection points, but im happy with how well it works for my first attempt. Placed the first piece of foam i sliced from the 8 ft block, and then cut the shape of the ribs. I'll be taking videos as i go along.<u></u><u></u></p><div><p class="yiv2989607409MsoNormal">Best Regards,<u></u><u></u></p></div><div><p class="yiv2989607409MsoNormal">David<u></u><u></u></p></div></div></div></div></div></div>_______________________________________________<div class="yiv2989607409elided-text"><br clear="none">
