I am going to be doing a major shop overhaul in the next couple weeks. I usually have around 7-800 bf of lumber in my shop of various varieties, thicknesses, lengths etc. Currently I have 3 huge multi level racks for storage to lay everything flat, which takes up a lot of floor and wall space. I'm thinking of eliminating that and standing everything on end against the wall in one location except the thin stuff and veneer. Am interested in opinions on storing lumber this way, does anyone do it and are there any issues? I am blessed with having 10 ft ceilings in my shop so most everything will work this way. Thanks
