How to make a hot wire foam cutter
WATCHING THIS VIDEO FOR CLEAR UNDERSTANDING
The part's
1. 12 foot, 16 guage extension cord, about $2 at Home Depot
2. 2 wooden yard sticks from the Home Depot paint department, $.97 each
3. 4 #10-24 x 1.25" machine screws with nuts, $1 at Home Depot
4. 10 #10 washers, $1 at Home Depot
5. About 12 feet of strong, low-stretch string. I used 200 lb dakron kite line.
6. A single-pole dimmer switch. About $10 at Home Depot.
7. A 25 volt, 2 amp transformer, $10.49 from Radio Shack.
8. An electric guitar string, about .10 - .16 size. I think around $1? You can get these individually at a music store or you can use either of the 2 smallest strings from a packaged set. You should keep a spare handy because they can burn out or break from too much tension.
9. A length of two conductor electrical wire with a regular plug on the end. I salvaged mine, but you could use another extension cord if you like.
10. A piece of wooden dowel or stiff plastic rod about one foot long (not shown). I used a bamboo skewer.
11. Optional: 4 regular-thickness CD cases. These are for the box that holds the transformer and dimmer switch, but you would be much better off with something like a "project box" from Radio Shack.
