I was thinking of copying this rack but instead of making it 4' high, I would make it 6' high. Since the melamine comes in 8'X4' pieces, I could have the first sheet cut into 2 pieces that are 2'X6' and 1 piece that is 2'X4'. Then 2 more sheets cut into 8 more of the 2'X4' pieces. That gives me the 2 6' tall sides and 9 4' wide shelves. I could probably do a few rows of 74qt tubs on the bottom, then maybe 4 rows of 32qt tubs in the middle and a couple rows of 6qt tubs on top. I might even have room for one more shelf actually. Depends on how high I make the sides of my storage area on top I guess... Will this idea work? Any advice?
