interesting.
I can only go from my very limited experience. I cut some wings out of some 2 inch pink foam. They where about 3 ft long with a metal "guide" the shape of the wing on each end of the foam.
I ended up using .042 welding wire streatched between the headstock and tailstock of a 8ft bed laith. This was about 10 years ago so it may be a little rusty. I just tried to take the slack out of the hot wire by moving the tail stock back (that didn't work)
I ended up puting a spring at one end - put quite a bit of tension on it and applied the power (from a 0-30 volt large power supply). I increased the current until the spring had lost a bit of tension and it cut beautifully.
