RE: [TCML] primary material? (interview)

Bob - 
I've also used romex, but kept it original.  In the flat insulated form you can coil it up into a flat spiral, and connect the three wires in parallel.  It doesn't look great, but it sure works in a pinch.

At the end of the gallery, you can see the romex primary hidden in electrical tape!  Ugly, but rugged!

(interview)> To: tesla@xxxxxxxxxx> CC: > > Hi Nicholas,> I made a TC primary with indoor romex 14-2 wire. Here's how: I stripped off all the insulation, outer jacket and the white and black leaving three bare number 14 wires. Secure one end each of the three wires with a vise or clamp to a solid work table. Keep the three wires straight and close together and using a drill gun (plug-in or cordless),  insert the free end of the three wires in the chuck that would normally secure the drill bit. With the three bare wires straight and suspended between the anchor vise and the drill gun, slowly turn on the drill gun and the three bare wires will eventually tightly wrap together forming a wider solid conductor. The diameter of the wire bundle is about 0.2 inches. The wire will set together and will not unwrap. You will lose some overall length as the wire wraps together so if you need 40' then I'd get a 50' box of wire (about $29. locally). It's not rocket science, the finished product looks nice and you> can say that you made it yourself.> Caution, use eye protection and watch out for kinks and mechanical forces stored in twisting wire (keep kids and pets out of the way) when wrapping the wire. Keep the wire stored in a loose loop until used.  > Good Luck,> Bob Wroblewski> Dracut, MA> > > > ----- Original Message ----> From: Nicholas J.
