Mike not sure if I want to make a thread on CNC foam cutting, but I will post my progress on this project. It helps document the process and seems for later reference. Greg sent me this and it has been helpful. http://tech.groups.yahoo.com/group/CNCFoamcutters/
TS, I got the airfoil thickness but not it the trailing edge. It almost close enough for XC but not for DLG, with some sandpaper or roller to thin it down. If I change the keft I may loose airfoil thickness and get the trailing edge correct. Trading one problem for another. Must be missing something.
