I've been reading through this thread, and it's very timely for me because I recently (about a month and a half) built a router for the purpose of making plane parts from foam and plywood. The machine isn't exactly scratchbuilt, since I used a lot of the parts from a CNC grinder I'd built a few years ago for grinding knife blades.

It is rather crude; Thompson linear bearings, aluminum, maple plywood, and I'm using a Dremel tool on it for now. Motors and controls are from a company called Microkinetics. It works remarkably well for such a cheap and dirty effort, but I'd like to improve it; I hope I can learn from you guys.

I have little experience in cutting foam, and speeds, feeds, and tool selection have been a matter of experimentation. Even with a motor speed control on my Dremel "spindle" the speed is a little too much, so I know that it's one of the issues I'll have to address.
