I drew this up not too long ago, it's basically how to cut the 8'x4' sheet of melamine that i would expect you will use for a rack. Holds 50 bins, all 6qt rubbermaids. Alter as you see fit, but hopefully it will get you started. The building is honestly just stack, drill, and drive. 2 racks, 100 babies, easy build. Just have fun with it, it's gonna take a long time hahaha. ~Caylan.S.~
