Looks like fun Phil.. lol...
Have you ever hot wired foam panels? It's pretty easy to make a system to do it out of stuff from your local home repair stores. I've had good success with a lot of projects. Here's a link to my auto cutter at work. Warning.. it's boring.
Also another link to my Pitts Model 12 model I just finished this spring if you guys have some time to kill. Now that this thing is done I am free for the next project. Hmmm..
