We were puzzled by the little belted-together blocks that were stuck between pieces of plywood alongside Bruce’s lumber rack, and received eye-opening instruction.
“Plywood or other sheet stock can warp, especially if it’s stored surface to surface. The blocks separate the sheets so air can circulate on both sides. Flat sheets from the lumberyard stay flat this way, no matter how long they’re stored,” Bruce said.
The leather is flexible, so you can use them on any combination of thicknesses of sheet goods.
The blocks are a snap to make from scrap wood and leather. Cut two 1-in.-wide strips of leather (or vinyl or heavy cloth) and space and screw 2-in. x 3/4-in. x 1-in. blocks along the strap.
“The air space also keeps them a lot easier to grab when you need to pull one out. For full sheets, use three sets of spacers, one at each end and one in the middle.”
