How to Glue up Boards to Make Wood Wider

plane true edges on boards that are bowed, cupped or twisted. Lay out the suriaced boards, refine the arrangement if you wish, then mark two sides of a large triangle across their faces, as shown in the photo below. The marks will help you maintain the order of the boards through all subsequent steps.

Jointing the Edges

Mating edges should be straight and square to the boards' faces; making them so is called jointing. You can joint edges with a hand plane or a machine jointer. Lots of woodworkers glue up boards straight from the jointer, and the joints are perfectly acceptable, but I prefer to combine hand and machine techniques. I establish flat, true edges on the jointer, removing lots of wood quickly if I need to. Then I plane off the tiny undulations left by the jointer knives and plane a slight hollow into each edge, so the joints "spring" together as shown in Fig. 3.1 think this combination of techniques makes for a tighter, stronger joint, but the difference may be apparent only to me. (If you don't have a jointer, you can skip to the section on hand planing.)

Jointing on the jointer—Machine jointing will be a breeze if you've flattened the faces of the boards, sharpened your jointer knives and set the outfeed table correctly. (See July/Aug. 1988 AW on tuning jointers.) Two edges make a joint; work them as a pair. Joint the first edge with the triangle-marked face against the fence and joint the mating edge with the unmarked face against the fence. Fig. 4 shows how al-

Basic edge joining skJIh let you glue up narrow boards to make wide ones. A triangular mark makes it easy to keep boards in order for gkie-up.

FIG. 3: SPRINGING THE JOINT

A »prang joint is tight at the ends, open in the middle. A good joint is slightly sprung; a gap of '/«-in. over 3ft is plenty.

A bowed joint, open at the ends, is likely to open up at the ends after His glued.
