The table is built from 2x4 lumber, and held together with drywall screws and dowels.
You will need a minimum of three 8' 2x4's, 28 2" drywall screws, one 3' long 5/8" dowel, some glues, a drill, and a circular saw.
Because 2x4's are not of consistent quality, but quite cheap, its best to buy one or two extra, so that you can avoid using any part with a defect in it.
