Wood Rack Design

    Why use sloping vertical supports?  It is a very inefficient geometry for storing wood planks.  I assume that it is for stability?  If you make the vertical supports 90* to the floor, you can space them two feet apart, use a six foot long horizontal support and store more lumber more efficiently using less floor space.  If you glue and bolt the vertical and horizontal members together, the assembly will extremely stabile.  If you want more stability, use 2x8s for the vertical supports.

    Actually, the angled vertical supports will add a lot of structural stability. With vertical supports, the structural frame is basically a rectangle.  Rectangles are subject to racking, which I believe will be a real issue with the weight that the rack will be supporting (unless the top and bottom of the uprights are secured to the building). Moving to an angled support structure, you can have a triangle superstructure.  Triangles resist racking. To get the stability of the triangular structure, you would have to add diagonal ties between the top of each support and the bottom of its paired support.  Those cross ties would effectively eliminate storage from the area between the uprights.

    Yeah, I'd guess either x-bracing or wider strips of plywood run the entire length of the rack would be the only way to fight the racking issue. That won't eliminate internal storage, it might just impede it a bit. I believe Rob mentioned this will be a stationary storage, so tying it to the ceiling and utilizing the upper area for acclimating lumber storage really would improve wasting space. I know Rob is enthralled with all the room he has right now, just wait a couple years!! LOL!
