Someone in the last 3-4 weeks had a posting on lumber rack.
Their angle was 10 degree with 1/2 black pipe for lumber holder.
Made mine similar that will fit up flush to the back wall.
With 8 wheels on the underside.
In the A frame part you can slip 4x8 sheets plywood.
My question is mine is 6 foot tall, with 18" spacing from left to right between studs total of 5 stud at 10 degree. Figure that will be able to hold on one step alone 2 boards side by side or total board width of 18" wide or about 20 boards 8 foot long.
My black pipe will perturd out 18" (pipe will be 21" long, with 3 inches into the 2x4) too hold two boards side by side on the shelf.
Will 1/2 black pipe 18" long be strong enough, or should one use 3/4 pipe?
Would think so with the 10 degree angle.
Need a fast answer as going to get pipe tommorrow.
