Some progress today. Scrounged up a few pallets and did some redneck carpentry and ended up with the Tower of Power you see below.
Pallets are 31" x 47". There's 14" between pallets on the bottom shelf and then 12" between pallets on the other shelves. I used 4x4's as uprights, screwed to the pallets using metal straps and some L brackets. And some 2x8's on either side. Will need to have some 1x4's or something like that running on the outside of the 4x4's to keep the saws from sliding out.
It's not going to win any prizes but it's functional and sturdy. The problem is that I really need to build two more of these and I'm running out of room.
