Here’s another one of those “why didn’t I think of that” tools: Rockler’s Clamp-It assembly squares. They’re just simple polycarbonate squares to which you can clamp any two pieces of wood you’d like to assemble in a 90 degree angle. Rockler suggests that they work weel for simple joinery, as a drill press jig, for drawer assembly, and for deck rails, but we can think of hundreds of other uses as well.
Clamp-Its aren’t just for the nuevo riche — they sell for only $12 each. Rockler also sells 5″ “Mini Clamp-It” bar clamps sized to fit perfectly with Clamp-It squares for $6 each, or for $5 each in quantities of four or more.
By the way, while you’re over at the Rockler site give their blog a look. They offer some pretty sweet free woodworking advice.
