[dorkbotsea-blabber] Phlatprinter - CNC for cutting foam sheets

[Josh Kopel]

Here is a link to an older but still excellent resource for building a 
3-Axis CNC foam cutting mill (and other low resource high-tech stuff).

He uses the mill to cut foam to be cast in aluminum.
Lots of great casting info as well.
