==Overview==
Hot wire cutters are used for cutting foam.  

== Existing Hot Wire Cutter ==
There is currently 1 completed foam cutter at the shop, built by Korc.  The power supply for the acrylic bender does a good job of powering it, but it should be noted that you might throw a power breaker using it, and that it is a dangerous piece of equipment that should be handled with care.  The wire cutter uses Nichrome wire.

== Brainstorms For Additional Hot Wire Cutters ==

* Proposed Capability:  Create several parallel cuts at once, in order to "grid" a piece of foam, similar to how Pre-Diced Pick and Pluck Foam is.
* Proposed Configuration:  Similar to an egg slicer
* Proposed Materials:  PVC pipe for the frame, 3 strands of Nichrome or Kanthol wire.  AC Transformer attatched to dimmer switch (similar to acrylic bender).
* Information Resources

*** Jeff has 32 Gauge Kanthol wire on hand
**** 1 ohm / inch.
**** 14 inches of wire per strand = 14 ohms
**** V=IR.  Assuming 6V max, I=V/R, I = 6/14, I = 0.43 amps-per-strand(&)
**** Total Amps = & * 3 strands = 0.43 * 3 = 1.29 amps 
**** Breaker should be rated for at least 15Amps, I don't believe this will throw any breakers.
