The idea behind doing the sections is to have them be solid.  Try cutting out the airfoils from thin wood 1/16" or 1/8".  I found it easiest to glue the printouts of your airfoil sectoins right to the wood and cut from there.  Have you tried using a hot wire knife to cut the insulation?  That is the way that most people have been cutting the foam in the past.

You can make the cutter from some dorbell transformers, and a dimmer switch.  You have to get a special kind of wire to run, like is found inside of hair dryers, and electric heaters.  Just be carefull that you get the biggest dimmer switch you can find, cause they can get overloaded easy.

"nichrome" wire is used as picture hanger wire. It can be found at just about any Kmart/Walmart/Home Depot/etc in a braided form.

Definitely superior to steel wire, though.
