Parts are 300w computer power supply, use 5v output wire. Two j boxes, one std outlet to be wired as 5v. Second j box has variable control. Two std two wire extension cords, i used 12ft., 1 inch pvc pipe, sweeps, and caps. 4 eyebolts with nylock and std nuts. Nicrome wire. I built my large bow to be able to cut 36" x 12" deep foam blocks, the two hand held wands i use 24" wire. The hand held rig runs hotter and cuts faster. The large rig cuts 48" in about 4 min. I did not put a bow tightner and so it cuts with slight arc as it cuts, nothing that has caused any issues with straightness. For straight edges i used two drywall squares which are 48" long, and with a couple of 3" screws they are held to the foam, and i draw the hotwire against them. It works pretty slick. All of the foam pieces i have cut have been done with these two rigs. Total cost, less than <span class="yiv0597078067gmail-m_-6538385522126439748gmail-m_8733938629245131009money">$30</span>.

Sliced the foam to 1/4" sheets, and trapazoid shapes to sit over each of the tribs. Then tapped it into place and then spray glued and tinfoil applied to protect the foam. Tomorrow a couple of coats of wax and then the first layer of matt glass. The inner shell will be attached to the exoskeleton to create the ballast tanks. Plan is 4 total, two aft and two adjacent to the rear pilot. Now that i got the form work dialed in, three more to go.<div><br clear="none"></div><div>David</div></div></div>_______________________________________________<br clear="none">Personal_Submersibles mailing list<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><br clear="none"><a rel="nofollow" shape="rect" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div>
