Fabricating Chainplate Wedges

Milling G10 kills tools.  I can barely do it on the home-made CNC.  I wanted a rather long wedge for my chainplate cores.  As I am only bonding the side of the wedges, the core could not be foam, but rather needed to be something that could handle a lot of shear.  In retrospect, I could have made these wedges maybe 2" in total length, but I headed down this path, and I am generally too stubborn to circle back.  The perforations are there to help avoid any problems with air bubbles getting trapped between plates and growing in size when pulling a vacuum.
