Note for Greg re: foam cutting
Commercial hot wire cutters have some design problems. They are limited in size so that you can't cut too far away from the edge. Also the wire is usually under a slight tension and makes a straight sided cut. Curvy sides need extra passes.
But you can cut the foam close enough with a knife and snap. And someone made shapers out of heavier wire.
Now back to the bridge.
