In this video, This Old House general contractor Tom Silva shows Kevin how to shop for lumber to build a workbench.
1. At home center or lumberyard, handpick eight perfectly straight kiln-dried 2x4s.
Avoid any board with excessive knots or defects.
2. Select one 4x8-foot sheet of ¾-inch-thick B-C fir plywood.
Check to be sure the plywood edges and corners aren't damaged.
3. For convenience, have the plywood cut to size by a home center employee at the panel saw.
