How to make strong lumber rack with 2x4's?

[CptanPanic]

I need to make a lumber rack to go onto my concrete wall. I was thinking of using 2x4's and tapcon concrete screws to attach to wall, but what is a strong way of doing the part that sticks out without having to put an extra angle 2x4 to optimize holding capacity?
Thanks,

the 2x4 stucking out from the wall sound good, just use a lot of hex bolts (carriage bolts rotate in 2x4's so easily, its not funny). If you find that you need more support, then you can add a diagonal support, because there shouldn't be that much lumber stacked on the shelves so you can sort throught them to find the best board. BTW, wood magazine published plans for a wood rack, which attached to a wall (I think it was concrete). And if you can, attach the rack to both the floor and ceiling to ad stability.

My lumber rack consists of 2x4 outriggers, roughly 16" long, attached to an exposed row of studs. I cut a half-lap on the outriggers *only* and thru-bolted them to the studs using two 1/4" bolts. This has proved PLENTY stout since the shoulder of the half-lap prevents the outrigger from rotating under load. No need for knee braces at all.

This picture sorta-kinda shows my rack. The top row of outriggers was already there when I moved in; I added the lower rows. Note that I tapered their bottoms slightly, to gain a skosh more room out at the front edge for narrow boards.

The vertical spacing of my outriggers is about 16", for roughly a 12" net space between each row. That's proven just about right. As Alex says, you don't want each space to be too large otherwise you'll spend way too much time stacking/unstacking.

Probably won't work in your situation - but might give you an idea or two - besides, I like showin' this off!
