MITERED THROUGH-DOVETAIL

You can make a through-dovetail with a mitered edge, creating a molded edge that goes the whole way to the joint. This joint is very attractive on serving trays or decorative boxes without lids.

Fig. 25A

NOTE: Depending on the depth of the molded edge, you may want to make the boards slightly wider to account for the molded depth. If so, mount the tail board so that the mitered edge will end with the thicker half-pin. With the offset guide set against the tail board, the pin board will automatically be cut correctly.

CUTTING THE TAILS

Cut the tails as you would a standard through-dovetail, except do not make the tail cut on the edge from the proposed miter.

CUTTING THE PINS

 

Fig. 26A

Step 1 - Cut all the pins normally.

Step 2 - Remove the template, turn it horizontally so that the straight fingers are facing you. Step 3 - Adjust the board so that the edge where the miter will be cut is to the left.

Step 4 - Adjust the board so that only the triangular part of the half-pin will be cut off with the router and straight bit, leaving a squared-off pin (Figs. 27A and 27B).

Step 5 - For repeated cuts, slide the left offset guide until it touches the pin board and secure it. Step 6 - Cut the triangular area off (Fig. 27C).

MITERING THE PINS

Step 1 - On the inside surface, use a square and pencil to draw a line from the base of the pins to the edge where the miter will be cut (Fig. 28A).

Step 2 - Use a table saw with the miter gauge set to 45° to miter the squared-off half pin (Figs. 28B and 28C).
