I have building plans that will give you 5 sets (10 total) of low boys out of 1 - 4'x8' piece of plywood. I'm not sure if you need that many though. I actually have 2 sets of plans: one allows for 3 larger sets to accomodate 8's. I will try to get both plans on Rowiki soon. If you can open an AutoCAD file (.dwg), I can email it to you, or anyone for that matter.
