The template and cutter supplied will produce dovetail pins and sockets approximately 3/8"

(9 .5mm) deep and spaced 1" apart. The purchase of a bearing guided straight cutter,

P152006A, will enable 1/2" wide box joints to be made in timber up to a maximum

1. Assembling and Mounting the Jig

Screw the front and top handles into the eccentric bars in such a way that the workpiece is

locked when the top handle is pushed away from you and when the lower handle is pushed

downwards.

Mount the jig to a firm and stable workbench at a comfortable height, remembering that the

router sits on top of the jig. The jig must be mounted close to the front edge so as to leave clear

passage for the timber to the front, vertical clamp. Also, leave ample clearance to the rear of the

jig to accommodate the longest length of timber you are likely to want to work a dovetail joint on.

There are two holes provided in the base for securing the jig to the bench. The front clamp holds

the side piece and the top clamp holds the front or back piece of the drawer. The complete joint

is cut in a single pass through the side piece (making the pins) and into the back or front piece

(making the pockets).

2. Preparation of Timber

As with all joinery work the drawer or box components must be sized and cut square accurately.

It is preferable that the width of the timber is in exact steps of 1/2" (i.e. 5", 5 1/2", 6", 6 1/2", etc.)

as this will give a series of fully-formed dovetails without part-formed pins or sockets at the ends.

The dovetail joints are cut with the insides of the components facing outwards and the edges that

will form the top drawer hard up against the side stops of the jig, therefore the right hand side of

the drawer and corresponding front joints are cut on the left hand side of the jig and vice versa. It

is a good idea to identify the drawer pieces as in Fig 2 so that they are positioned correctly in the

jig.

Front and back pieces 1/2" (12mm) to 11/4" (32mm)

Side pieces 3/8" (9mm) to 3/4" (18mm)

thickness of 3/4"(19mm).

Fit the bearing guided cutter securely into the router collet and then set the cutter depth,

preferably using a fine height adjuster, until the bottom face of the cutter protrudes below the

router base by between 15 and16mm (see Fig 7). Allowing for the 6mm thickness of the template

this will give a nominal dovetail depth of between 9 and 10mm. In some situations it might be

found useful to fit a 3mm packing piece between the template and the timber in order to give a

better contact between the bearing and the slots in the template.

The cutting depth is critical to the final fit of the joint, with as little as 0.5mm change in depth

making all the difference. A number of trial cuts will probably be necessary, with adjustments to

the cutter depth being made to achieve the best fit.
