FITTING THE JOINT
Adjustments may need to be made depending on the
resulting fit of the joint. If all of the problems below apply,
fix them in the order listed below.
1. TIGHTNESS OF FIT
To adjust for tightness of joint fit, see the diagram on
the half-blind bit depth gauge (Fig. E14). A shallower
bit depth will make a looser joint. A deeper bit depth will
make a tighter joint.
RE-CUTTING THE BOARDS
After making the adjustment, the boards need to be
squared off and the joints re-cut.
2. FLUSHNESS
If the end grain of the pinboard (A) is recessed (too low,
as shown in Fig. E15) or if it is too proud (too high, as
shown in Fig. E16), the template can be adjusted to fix
this.
NOTE: For recessed joints, the fix below will adjust the
stops so you can push the template back further before
re-cutting. For proud joints, the fix will adjust the stops so
the template will be brought forward before re-cutting.
TO CORRECT RECESSED PINBOARD: Loosen hex nut
(GG) Fig. E17 and turn stop screw (FF) Fig. E17 or E18
clockwise if the joint is recessed.
TO CORRECT PROUD PINBOARD: Loosen hex nut
(GG) Fig. E17 and turn stop screw (FF) Fig. E17 or E18
counter-clockwise if the joint is proud.
NOTE: The steps above are also detailed on the template
label "B Tails".
RE-CUTTING THE BOARDS
After making the adjustment, the boards need to be
squared off and the joints re-cut.
NOTE: Be sure to replace the template (D) Fig. E18 firmly
against new stop positions before making the router
cut.
