RABBETED HALF-BLIND DOVETAILS
To produce rabbeted half-blind dovetails (drawer front), cut
the pins for a half-blind joint after the drawer front has been
rabbeted. The depth of the rabbet must be deeper than the
half-blind router bit depth guide.
NOTE:
Cut the tails first.
For miniature half-blinds, use the 4215 accessory
kit.
Use scrap wood until you are comfortable with the
jig.
Mount the correct offset guides - black for the
standard and silver for the miniature.

CUTTING THE TAILS

Step 1 - Clamp a scrap board (A) Fig. R1 in the upper clamp (horizontal mounting position). Use scrap board that
is thick enough to prevent the bit from contacting the base (1/2" will work). Secure the template (B) on
top of the scrap board (Fig. R1). Ensure the flatness by holding one hand on the board and using the other
to tighten the template knobs.
Move the left offset guide all the way to the left (Fig. R2). (Use the black offset guides for the standard
Step 2 -
cut, and the silver for the miniature cut).

against the jig base (Fig. R3).
