Project help

What kind of wire are you using? A Nickle Cromium wire probably available from radioshack and a 12 volt battery should work quite well.

I started by using a copper wire.The lenth was about a foot.At one point it worked but the battery got hot and freaked me out.I'll take a ride today and let you know.Just to let you in on the project.I'm making RPG diffusers.Not perfect but the prototype works fine.

While i haven't done anything like this, i think that a band saw would work pretty well. Just a guess though.

As far as your "wire saw" goes, be careful in regards to the fumes produced. I would make sure that you had plenty of ventilation and were wearing some type of mask.

In terms of what you are using for this wire saw, if you've got a good sized variac with a fuse on it, that's what you need. I would not use copper wire for several reasons. As Rives mentions, nickel chromium wire ( the stuff that they use for toasters ) would be ideal. I don't think that Rat Shack has this, but it would probably be worth checking out. Sean

the fumes were bad.I will be using a resperator.Saws are out as they make a mess and require me to sand to a paintable finish.Thanx guys.Keep the idea's coming .

sean,I checked out some variacs on line and it's all coming together.I must now go to the,"surplus store".These guys have everything and cheap.I built a switchbox that turns on my triggerless amps for peanuts.All five amps using seperate 20a lines,overkill....absolutly.

The copper wire's resistance was probably too low for the battery. Use what Rives suggested.

Be careful with the variac. Most of them are not isolation tranformers, so your wire "blade" and its associated wiring will be electrically "hot". Touching it and a ground simultaneously would be very unsafe.
