Dovetail Dados (Sliding Dovetails); Dado Board - Porter-Cable 4212 (29550) Instruction Manual

Step 5 -
Clamp the second workpiece (A) Fig. S11 in the lower clamp (vertical mounting position) on the right side
of the jig flush against both the template (B) and against the right offset guide (C) with the outside surface
facing away from the jig.
Step 6 - If the first and second workpieces are of different thicknesses, reset the router bit depth using the
"tails/box" bit depth guide.
Step 7 - Rout between the fingers of the jig with the templet guide against the left side of the fingers, both in and
out. This light pressure toward the left will help to prevent loose joints (Fig. S12).
Step 8 -
Remove the second workpiece and assemble the joint (Fig. S13)
NOTE:
The fit (tightness) of the box joint cannot be adjusted.

DOVETAIL DADOS (SLIDING DOVETAILS)

Dovetail dadoes (sliding dovetails) are used primarily in the construction of cabinets, entertainment centers and
shelving. The 4200 series jigs have three preset depths for dadoes ( 1/4", 3/8" and 1/2"), but you can manually set
your router bit depth to any setting.
NOTE:
Be certain that the router bit will not cut into the base or offset guides during this cut.Everything is provided
for this cut in both the 4210 and 4212 jigs.
