Porter-Cable OMNIJIG 55160 Instruction Manual page 52

NOTE: Be sure to space the fingers (J) around the
tall edges (K) of the workpiece, as shown in Fig.
G6. Maintain 1/8" gap at (L).
Before making any cuts, be sure you
read your router owner's manual for safe operating
instructions.
NOTE: Remember that the tail height (F) Fig. G7 (or
router bit depth) can't be greater than the height of
the rabbet (G).
4. Make the cut using instructions included in the
variable-spaced half-blind joint section. Final
cut should look like Fig. G8.
CUTTING THE TAILBOARD
1. Be sure pinboard is removed and template is
flipped over so "B Tails" label is showing on
top left side.
2. Place scrap boards - one is shown at (N) Fig.
G9 - in horizontal position and bring template
down.
3. Place your spacer setup block (C) Fig. G9
flush against left edge guide (I).
4. Position the tail board (drawer side) (B) Fig.
G9 in vertical position flush against the spacer
and up against the template with "outside
surface" against the jig.
5. Position the horizontal scrap board (N) Fig. G9
forward against the back edge of the tailboard
(to help reduce tear-out).
Before making any cuts, be sure
you read your router owner's manual for safe
operating instructions.
6. Make your cut, according to your instructions
for variable-spaced half-blind joints. Final cut
should look like Fig. G10.
TIP FOR COMPLETING A FULL HALF-BLIND
DRAWER
If you are making a drawer that has half-blind joints
at all corners and you want to retain the same
finger spacing all the way around, use the spacer
(C) Fig. G9 when cutting the back pinboard. When
mounting the back drawer pinboard horizontally,
simply offset the board using the spacer in between
the board and the left edge guide before tightening
the workpiece and making the cut.
