Re: foam cutting current ?

Just got this through from a member:

"Since the heat (energy) is not used for cutting, but for
overcoming the latent heat of fusion of the foam, all of your
observations are right on the mark.

I'd suggest a force feedback arrangement, since it will ultimately
be wire tension that will detect whether or not the foam is
solid or molten.

Tried to post this from my newsreader, but I'm registered
under a different ID and I'm too lazy to go to the website / yahoo
group to post (also too slow on dialup).

Feel free to forward to the yahoo group if you wish / mark in BC
Canada"

So I did, sounds like a really nice idea. Three pulleys and a load
cell would be one way to do it.
