large circle cutter for foam or gator core?

[CropMarks]

Hello, I've searched the internet, this forum and even between the couch cushions.... does anybody know of a way... or a tool... that can be used to cut large CIRCLES out of a piece of foam core, gator foam or styrene? Does anyone make something to attach to a dremel tool? or something else?

Any help would be great! thank you very much! miked.

Aside from a flatbed router or similar CNC setup, the occasional cut you could do with a plunge router. Use a colllar to ride a styrene (0.060") template of the circle made by scoring it with a trammel scribe.

Rigidly secure the dremel (or jigsaw or router, etc). Drive a finish nail through material at circle center point and into table. Slowly spin it while humming that "Convoy" song from the 70's.

You need a circle jig. Google it.
