doesnt the aluminum arm get hot as well?
-
Which pelican case is that?
-
so much better demo than the sloppy carving knives. probably closest method to die cut. thanks for video!
-
Do you have a link to the wiring diagram?
-
I do have another question however...how did you attach the aluminum barstock below the deck of the box. Also, what are the dimensions of the box you made?
-
Does the wire cauterize the foam or leave a crust on the foam?
-
The wire is clamped to a terminal on the bottom. Yes I made sure the wire was plumb and I marked the bar to ensure my cuts are accurate.
-
Having watched your second part I can see now how the wire is connected on the top but, how is it attached at the bottom. Also did you use a level to find the barstock marking point?
-
It is a solid bar of aluminum
-
Thanks for the video. Is the aluminum rod hollow?
-
Hi Could you please tell me exactly what dimmer switch you used from radio shack? I live in New Zealand and we can't get heavy duty ones so i will be shipping one internationally from the US
Cheers

That looks really great (the cutter and the completed foam)! one question... is the aluminum arm part of the circuit? or is there a wire running through it to the ni-chrome wire?
-
How much would you charge if I send you the sharpee markered foam and you cut it and send it back to me?
-
learn how to turn the camera sideways !
-
A part 2 on how to put one together would be great. Along with how you initiate the cut
-
Would you be interested in making one of these for me and selling it to me?

This is a quick video of a Hot-Wire Foam Cutter that I built with a 120V to 12.6V 2 Amp Transformer and a Dimmer Switch from Radio Shack. I used 26 Gauge Ni-Chrome wire that physical properties are not effected by high heat. This allows the wire to get red hot under tension and cuts foam easily with professional results.
