After a recent comment I made on a previous post about cutting Foam Letters I received a number of e-mail requests for the design.
A picture is worth a thousand words ....

Gday Jon,
Nychrome wire from Dick Smith etc. works well in these things too.
Reminds me I must see if the screen printing shop I lent my home made hotwire to is still in existence and if so GET IT BACK!
Have you got any type of control to vary the current apart from 6v/12v setting on the charger?

Thanks Jon! You're right, a picture is worth a thousand words! Just happen to have one of those chargers around the shop. Robin

I guess a battery charger would work for a power source in a pinch. I prefer varible transformers myself. (Also known as a variac) Here's a photo of one of the models I have...

You just dial up the amperage to the proper level for the length or thickness of the wire you are using. I have a 10 amp that powers my cutting table and I have one for a slab cutter and hand tools. I've run 10 ft. wires off these things and never had one past 40%. These babies aren't cheap though. They run from $250 to $350. A lot more than a battery charger but if you're serious about cutting foam, this is the way to go. The ones I use are made by Staco Energy of Dayton OH. I've been sculpting foam for twelve years and I swear by these things. The one powering my cutting table is 8 years old and I've abused the daylights out of it. I use nychome wire on the table but you can get away with aircraft safety wire if you have to. As for the hand tools, I use what I call paddles for lack of a better word. I use thick nychrome wire bolted to wood paddles and bend them into shapes so I can use them like clay sculpting tools. You can bend them into any shape you want and they hold their form while heated. I finish off the detail with a dremel. Believe it of not, these vultures I made for the zoo are actually made out of EPS foam...


You can make some very detailed items out of foam. Happy cutting!

cool jon,
i remember the faces of ppl at the national meeting in hervey bay when devo made up a hot wire to cut foam....
oooh ahhhh how do you do that?

it was great

we mostly use the router to cut foam letters but i like to carve foam and the tools i've collected need a shed all of their own nowdays

my hotwire used puter bits n pieces for its go juice... ive allways got them lying around

and i agree with bloke, nicad from dickies is the cheapest/best way to go

good on ya mate

cheers

You can also use a 1000 watt flood light,
and stainless steel fishing leader,my dad once wired up an old projector to a hot wire LOL.
I used one like that for years before I found
that router with a vacuum was better for your lungs and smoother and straighter on the turns than a hot wire.

PS:
Nice Vultures, I may try that on seagulls!
maybe they will stay clear of my Mercury
with a few vultures sitting around LOL.
