We cut the supports 16 in. long, but you can place the second shelf at whatever height you like. Screw the end supports to the walls at each end. Use drywall anchors if you can’t hit a stud. Then mark the position of the middle supports onto the top and bottom shelves with a square and drill 5/32-in. clearance holes through the shelves. Drive 1-5/8-in. screws through the shelf into the supports. You can apply this same concept to garage storage. See how to build double-decker garage storage shelves here.
To corral shelf-dwelling books or DVDs that like to wander, cut 3/4-in.-thick hardwood pieces into 6-in. x 6-in. squares. Use a band saw or jigsaw to cut a slot along one edge (with the grain) that’s a smidgen wider than the shelf thickness. Stop the notch 3/4 in. from the other edge. Finish the bookend and slide it on the shelf. Want to build the shelves, too? We’ve got complete plans for great-looking shelves here.
The bench would end up being about 5 feet long. I thought about cutting 5 feet out of my 8 feet long countertop and use the rest for a small support table. However, after a consideration, I decided to bypass the front vise altogether together with the overhang so my bench will be 4 feet long. This allows me to skip the MDF and just glue the two halves of the 8 feet board together.
Beyond the weight capacity, the Grizzly is also the largest table top on our list and in more ways than one. For a workspace, the Grizzly provides 5’ of length by 2 ½’ of width. There is not another table that really comes close to that size. Another size advantage of the Grizzly bench is the table top’s thickness. While the standard thickness of the table top for a quality woodworking bench is 1” with lesser models often offering only ¾” of thickness, the Grizzly provides a 1 ½” thick table top.
