I have roughly 350 board feet of 3 quarter hard maple (8-10 ft lengths), 300
board feet of 3 quarter cherry (8 foot lengths) and 200 board feet of other
stuff in varying lengths. The maple and cherry I purchased through a Craigs List
ad and had been surfaced and thicknessed top and bottom and 1 side.

To date, I have been storing the lumber as I use it in 3 stacks on bottom sticks
which rest on epoxied concrete. I have not inserted sticks between the board
layers. I live in an art loft that was built in 1916 as a boot factory. The
floors and ceilings are 18 inches thick. The ceilings are 12 feet high.

I am having thoughts of building leaning racks against the out side walls to
store the wood on end similar to what I see at lumber stores. A lot of floor
space would be saved with this method.

Is leaning/standing the boards on end a method of storage that does not
encourage warping and twisting over time?
