I.D. OF TEMPLET GUIDE
Fig. 22A
Cutting a dado with a templet guide that has an OD smaller than 3/4" requires two passes.
1. Start on the left side. Keep the router toward the back edge of the dado slot, and cut to the right until you have
completed the cut.
2. Start on the right side. Keep the router towards the front edge of the dado slot, and cut to the left until you
complete the cut.
3. Leave the router in the dado slot until the bit stops spinning.
NOTE: For deep cuts, use a straight bit first.
NOTE: Cut the tenon just as you would a standard tenon.

HALF-BLIND DOVET
AILS WITH TAIL BOARDS THICKER THAN 7/8"
For tail boards thicker than 7/8", you can use the template normally used for through dovetails (instead of that used
for half-blind dovetails) to provide deeper pins and tails (Fig. 24A).
The procedure is the same as that for a normal half-blind dovetail.
NOTE: Use the “half-blind” line for aligning the template.
Fig. 24A
With the wood clamped to the base of the jig, the maximum thickness will be 1-1/8". By using a templet mounted
to a clamping board, you can use much thicker wood, producing a strong joint.
