FINALLY!!!!! Its finally time to put all of this to work.
Clear your workbench of everything. If you leave a washer on the workbench, you'll have a great little circular indention in the foam when you're done...
Before you cut good parts, put a scrap of depron under the pattern and cut a test cut to ensure you have the depth right. Milling ultra deep does not seem to eliminate a ton of weight, so go 1.5mm - 2mm deep into the foam.
Once you are satisfied with the depth, lay your cut parts on the bench arranged so the milling pattern will fit over them and lay the milling pattern in place. Get the parts arranged inside the alignment shims you glued onto the milling pattern so they will stay put.
Start up your router and drop the cutter in the center of the hole to be cut out. I like to trace the outline of the hole with the router then move in a zig zag pattern across the face of the hole with the router to 'clean it out'.
Move your way accross the entire part until you've milled out all your holes.
You've done it! You have milled a part and reduced its weight
