The top is constructed using block-laminated beech 1-3/16" thick. The Large Bench is 19-1/2" wide and 67" long overall and weighs 112 lbs. The X-Large bench is the same width and is 79" long overall and weighs 124 lbs. Both are 33-1/2" high. Each has two clamping Vices with solid steel guide rods and an acme threaded screw, and a shelf below the top between the leg trestles as shown. Four rows of round bench dog holes (two parallel rows for each vice) and four round steel dogs with one flat face, plus extra dog holes in the legs to support large panels on their side, complete the picture. A moderate amount (15 to 30 minutes) of assembly is required."
