With the shelf secure, get a couple of friends to come help, and stand the bench on its feet. I said earlier moving the top by yourself is dangerous. Trying to lift the entire bench is foolhardy. Of course, I already said I'm stubborn, so I did it myself by rigging a simple block-and-tackle using lightweight pulleys I got at the hardware store. (Not the lightest-weight pulleys, those are meant for flag poles and have a design load of something like 40 pounds. These had a design load of 420 pounds.)
A woodworker's workbench isn't a table, it's a work-holding system. It's not something you set things on top of, it's a tool that holds your work. Where a worktable might have a machinist's vise bolted to its top, a woodworker's bench is built to accommodate a number of different workholding mechanisms, such as bench dogs, planing stops, hold fasts, or board jacks, and will usually have one more woodworker's vises integrated into its structure.

Thanks! Great information. As an advanced novice worker, I finally decided to build my first bench a couple years ago. After reading several of your blogs knowing full well mortised dove tale leg joinery is yet beyond my capability, I elected to build Robert Lang’s “21st Century Workbench”. I also chose his VERITAS Twin Screw Vise in the face vise position. Used an old Craftsman face vise in the tail vise position. Constructed of laminated 9/4 x 31/2″ Pecan and 60″ long because of my small crowed shop. Super happy to this point. As I mature in woodworking I may live to construct one of a different choice at a latter date, but I’m 73 so we’ll see. Thanks again for the advise.

I was using 2-1/2" coarse Kreg pocket hole screws. Kreg screws are supposed to be self-tapping, but the coarse-thread screws are intended to be self-tapping in softwood, and the fine-thread screws they intend for use in hardwoods aren't available in 2-1/2" lengths. I decided to drill pilot holes in the oak. Just to make sure, I did a test hole in the scrap piece I'd cut off.

Lay a leg flat on your work surface, with the countersink side of the thru-holes down. Stick a piece of threaded rod in each hole. Take a stretcher that is marked to have one end adjoin the top of this leg, stick a dowel center in its dowel hole, line it up against the leg, using the threaded rod for positioning, You want the top of the stretcher to be even with the top of the leg, or just slightly above it. Give the end of the stretcher a whack with your rubber mallet. This will leave a mark indicating where the matching dowel hole in the leg needs to be drilled. Repeat with the lower stretcher than adjoins this leg. Then repeat for the other leg that will form this trestle, and the other ends of the two stretchers.

Still, one of the best features about this woodworking bench has to be its vices. First off, the Sjobergs provides two vices both as sturdily constructed as the bench itself. The same hardware that fastens the bench works to ensure the vices are just as strong. The next main benefit on the vices in the inclusion of multiple positions – four in total – for the vices to go. This allows you to mix and match to suit your needs and allows the table to be used just as easily by right-handed and left-handed users.
