Re: Reupholstery -- Spitfire seat foams

[Philippe Habib <phabib@apple.com>]

For cutting foam, you can get some nichrome resistance wire with a variable 
voltage supply, strecth it on a frame of some sort and sort of melt through
it.

Where I used to work, they used the MIG welder.  Feed out a few feet of wire
and ground to far end at low power to get it warm.  Worked like a charm.
