Edge Joining Boards

Edge joining boards is a common method for creating wide boards from a series of narrower boards. The Domino tenons add strength to the joint and also assist in aligning the boards to be flush.

For edge joining boards, a series of tenons are placed down the length of the joint. The first tenon is used to register the two boards horizontally, so it is milled at standard width.

The remaining tenons align the boards flush and may be milled with an oversize width.

Tips for Successful Joining

►► Use the stop pins (page 11) for the first mortise slot with the mortise width lever set to the narrow setting (page 8).

►► For subsequent mortise slots you can keep the mortise width at the minimum

setting, but you may find it easier to set the mortise width dial to the next widest setting.

►► Place the mortise slots 6 to 12 inches apart for standard joints, but this spacing should be decreased for joining plywoods or when a stronger joint is needed.

►► Instead of marking the mortise placements with pencil lines, you can use the optional Cross Stops (page 12) to evenly space the mortises down the length of the boards. To do this, use the stop pin in the previous mortise slot.

Making Miter Box Joints

Without tenons, miter box joints are fairly weak because the joint is predominately endgrain to endgrain. Tenons signifi- cantly increase the strength of the joint and make it easier to assemble and clamp the pieces.

Construction Tips

►► For thinner materials, keep the mortise close to the inside corner. This minimizes the chances for boring all the way through the workpiece.

►► For very thin materials, it may be necessary to shorten the Domino tenon length as described on page 18.

►► For thicker materials, stacked mortises can be used.

Setup and Machining

1.Tilt the fence to the appropriate angle. (Refer to the table on page 7 for miter angles for multi-sided boxes.)

2.Lower the fence to the desired height. Note that the mortise should be close to the inside corner to avoid penetrating through the workpiece.

3.Tip: Before milling the mortise, double check your depth settings to ensure you don’t cut all the way through.

4.Plunge the joiner as shown below.

5.The stacked mortises are used for thicker stock.

6.Grasp the joiner by the auxiliary handle for best control.
