Here's an image of what I'm currently planning for my vac zones:
ShopBot Deck Layout.jpg
Our stock material sizes are 4x8 and 5x5 each of which end up being 3 zones in this layout. My kit includes PVC hardware for (6) zones.

Any comments or feedback on this design?

Looking at my table drawing, I'll have to shift my "port holes" to clear framing members, but I can finalize those once I have the table frame assembled.
