@SirGeekALot here are the drill guides I used. https://drive.google.com/folder/d/0B1rU7sHY9d8qT0J1RVBSeV9LdU0/edit
The only hard part is the holes for the 10mm rods to go through the 20x80. It is half on half off a rib. It would be best to cut those holes with an end mill style bit than a standard bit to avoid bit walk.
But the rest are easy with the printable guides: https://plus.google.com/app/basic/stream/z13bx1kzpxn1ibmdv23qs3cw1mnkhr5dz?cbp=1uwgm8rnm1h13&sview=28&cid=5&soc-app=115&soc-platform=1&spath=%2Fapp%2Fbasic%2Fs&sparm=sc%3Dpo%26sq%3Ddrill%2Bguide
