Got any pics?

Glenn, you are going to have to design us a roundover wire cutter that runs on 4 D sized batteries...

Mike...

Mike, heres some links to more battery operated cutters.

Have seen some pics of people using plug in power adapters and I think I'll go the the local 2nd hand store and pick up a couple of different types and experiment.

oh no, does this mean i have to watch allan also?

i do like that cut though, nice

Do you have any examples of wire cutters that can cut a roundover?

Mike....

I would like to see that also. It seems the only way it would work is with a piece of thin stiff flat material. It would keep it's curved shape, and wouldn't bend like round wire especially on a large radius.
We have these at work (see link). I think this would be stiff enough for a roundover cut, but I don't know how much current would be required to heat it enough. These are 1/4" wide, but it looks like there is also a .177" width. They are very thin, and would cut like a knife .015" thick.

It could be formed to shape similar to the Ohms Symbol, but with the legs further apart formed to the desired radius.

This should do the trick simply (found on internet).

That looks good. Tell me where I can get that wire... and of course, please tell me what kind of wire that is...

Mike both excellent questions and all I have for you are silly answers. I've only started to learn about hot wire cutters in the past week and so my humble self pleads ignorance. GPW, pete42 or Larry C would be a better source of opinion at this point. At this point in my learning I'd just grab whatever wire I had hanging around and try it.

It's nichrome wire http://en.wikipedia.org/wiki/Nichrome and you can get it here http://www.amazon.com/Nichrome-Nickel-Chromium-Guage-Length/dp/B0046VZJVO

Here’s another take on a quickie HW foam cutter ... http://www.rcgroups.com/forums/showthread.php?t=1244763

BTW, lots of HW cutting info on this site .... use the search function ...

GPW thanks for the link. Bought a power supply on ebay and it's on its way! Found my beginners website - uncomplicated info about power supplies, tool plans, wires, good video links, etc. Time to start building a table and tools.

Lots of good info out there , one only has to search for it ...

just came in the mail ... TEC 3 Power Command 9000. Output is 20Vdc, 19VAC, 20VDC - all no load ratings. I'll have to find out what that all means. And it's got dials, switches and meters .... ohhhhhhh

Looks Cool ... dial in the Heat ...
