Build steps
Cut three uprights to 94 in and twelve arms to 36 in, with a 10° bevel on the outer end of each arm.
Find the wall studs 16 in on center, and screw each upright to a stud, 46 in apart, with three 3 in lag screws.
Screw the arms flat to the front of each upright at 14, 38, 62 and 86 in, with two 3 in screws, and a scrap block under each.
Lay the lumber flat on the arms, longest at the bottom. A 2x4 bar at the end stops boards from sliding off, if you like.
Before you start
Four levels of arms 24 in apart hold boards and plywood strips; each arm carries about 80 lb. Anchor the uprights to studs, not to drywall alone.
The arms tilt up by 10° so the boards stay on. Check the bevel on a scrap before you cut the lot.
A rack for 8 ft boards needs the arms every 48 in; the ones here are 46 in apart.
