GoE Labs: How-To!,Hot-Wire Foam Cutter, Core, variable power, Power Supply, for $20
Hot-Wire Power Unit:
Don't forget the accessories like the
Steve O The Mach 11 Foam-Erator Extreme (Turbo) How-To (deluxe Scroll saw unit) !
Also see the much simpler GoE Labs: How-To, The Mach 2 EZ (also Turbo) Anyone Can Make HotSaw..., inspired by Steve_O's but way easier to build !
Power Unit
shown with Optional switch/outlet combo +~$7.00
(because I always need another plug for something)

NOTE: if the PET-120-12-60 is out of stock the PET-120-12-75 will work nicely also The 75 is 75 Watts ( vs 60 Watts) it otherwise a form fit and function equivalent. It will heat the wires a tad more on full power, and could cause hotwires to burn out faster, but that is what the dimmer is all about.
Notes: Initial testing shows that a 1 foot section of the guitar wire works pretty well. The whole string was tested also and it too will cut ....
General simplified schematic of the circuit,
(shown with outlet and switch)
Notice that it was necessary to trim the aluminum on the dimmer so it would fit in the box correctly. This is usually for heat dissipation, but we are not even close to needing it
General Arrangement with initial wiring in place

yes the diagram is correct, and it shouldn't matter which black. Check the docs with the dimmer just to be 100%,
I've not seen one that needs a specific black.
If they're both black with no differences eg stripes dots etc, then it doesn't matter

Comment by Nick Miller on September 23, 2009 at 10:20pm - But that wiring diagram is accurate, otherwise? Does it matter which black wire on the switch goes to the black wire on the transformer and/or power cord?

Perfect. I have used click off rotary dimmers, not Push on/off ones .
The problem with the push on/off is you're never sure if its on or off.
I added the switch, so you could dial in your optimum cutting temperature, and just flip it on and off at a consistent temperature, but that is the beauty, if you don't want it, you don't have to.

Could one just as easily use a push-button rotary dimmer? I imagine it would free up some space in the container. I'm new to wiring, but this is my situation: I've got a dimmer with 2 black wires and a green wire. the power cord, like any power cord, has a white, green, and black wire, and the PONY transformer has a black and white wire (and of course the two blue ones)

can someone verify whether or not the diagram above illustrates the correct hookup for this?

- See steves cutter the G string is bout the right gauge for cutting

What happened to the G string? Don't tell me you were overcome with modesty...
How is the wire manipulated to create various shapes and cuts? I'm guessing you wear gloves and bend the G string as desired...? Are there options to the G string to enable etching or other techniques?
