I was ready to ask this question, but decided that I would simply google "Lumber Racks." All of the pics that came up were of horizontal racks and after using horizontal racking for a few years, I am done with. "I know it is in here. Onward!" With a vertical rack I can at least turn the wood within the rack rather than lifting, pulling moving, uncovering or putting someplace else while the voyage of discovery continues. I am going to build an 8' long rack with 12-18" adjustable bays that can handle up to 10' pieces. Two levels for the shorties. It will be mostly wood, but possibly some unistrut, metal, etc. There is no question that the real answer to any of these types of things is self-discipline, and on occasion I'm pretty good. I'd be much obliged for any ideas or successes you have had. Gotchas are always appreciated. What do you like and why?
