Routing Your Offset-Front Joints
You are now ready to rout your first offset dovetail joint. As
mentioned earlier, you should make a trial cut with scrap
pieces of the same wood used for the finished work. Us-
ing scrap pieces allows for adjustments to be made in the
following steps.
• Place the router so that the subbase is resting flat on
the dovetail template. Make sure the cutter is not mak-
ing contact with the edge of board (A), then turn your
router on and let the motor build to its full speed.
• Make a straight cut from RIGHT TO LEFT across
board (A). See Figure 25. This shallow V-groove cut is
made to prevent chipping of the wood when the router
is moved in and out of the fingers of your dovetail tem-
plate.
NOTE: When making 1/4 in. dovetails, one or two extra
passes may be necessary to cut away excess stock
projecting beyond the fingers of the template.
Fig. 23
• Attach comb-shaped template (F) to the dovetail base
with washers (G) and spacers (H) in their desired loca-
tion. See Figure 24.
• Hold the template flat on the boards with one hand,
and tighten template clamping knobs (E) securely.
NOTE: Be sure template finger ends are parallel to
edge of board (B) to assure even fitting after cutting.
