<p>The whole idea of the dimmer was to act as a safety. If the Variac was set to 9-12 volts, doesn't matter what you do with the dimmer (or light switch for that matter) voltage will never go over 9-12 volts.<br/><br/>So is it the AC that everyone is worrying about? I can sell the variac on ebay...</p>

<p>I've used a hot wire for years to cut foam for model airplanes. The first thing you notice is his use of a 12V battery charger. This doesn't eliminate the burn risk, but brings the voltage to a safe level.</p>
<p>Modern battery chargers are electronic, and won't work... you need an older one that doesn't auto-cutoff or look for a battery. (Basically, see if it produces 14ish volts with nothing connected on the battery end.)</p>

<p>And no, a household dimmer is not necessary...</p>

<p>what you need is a cover that closes a switch when closed. as well as 2 other buttons in series,one either side of the cover. make it so the wire can not get hot unless all 3 switches are closed. ie place the wire where it is to burn. close the lid press the left switch with the left hand and the right switch with the right. </p>

<p>Touching the business end of a soldering iron will burn you. Touching anything red hot will damage you. Having something like that out in the open is asking for trouble. </p>
<p>Do what you want, Just saying that setup is insanely dangerous. </p>

<p>Completely incase both the electrical hazard and the heat hazard so there's no way to come in contact. This would also insure no moisture would touch the heating element. You would have to come up with a way to line the fretboard up without ever directly looking at the element. Possibly a templet and peg system for each scale length needed. </p>
