40
Chapter 10 Super Jig-12-18-24 User Guide
10-9 Board Widths: To achieve equally sized half pins
at each side of a fixed space joint, use chart width plus up to
1
⁄4"[6mm],
or chart width minus up to
1
⁄8"[3mm]. This chart covers boards up to maximum width for each jig. Pin centers
will always be ⅞"
for Single Pass Half-blind dovetail joints.
Example: the 7"[178mm] can be up to 7
1
⁄4"[184mm] or as small as 6
7
⁄8"[175mm].
Note: This test joint is for
3
⁄4" thick drawer front,
1
⁄2" thick drawer side and #80-8 dovetail bit. Scale settings and depth of cut will vary
depending on bit selection and tail board thickness.

10-10 Slip the Spacer onto the left hand front side stop
, note:
No 1 to the top. With the finger assembly raised in the
H
HB Tails
mode, clamp a drawer side in the front left side, against the Spacer
and the top end edge slightly above the jig body top.
Note: Drawer side thickness can be from
7
⁄16" to
9
⁄16"[6 to 14mm].

10 -11 Place the drawer front (from
1
⁄2" to 1" thickness [16 to
25mm]) in the rear clamp. Clamp with the side edge against the
left rear side stop, front end edge touching flush across the rear of

10-12 If you're mounting Thin Pin Boards:
Minimum recommended pin board thickness is
1
⁄2"[13mm].
Remember, No.128-8 bits rout at
3
⁄8"[9,5mm] deep. If you rout
a pin board less than minimum thickness
, you need to pack
the board up from the jig body. We suggest a piece of
1
⁄4" to
3
⁄8"[6
to 9mm] plywood for this purpose
.

10 -13 Re-set the drawer side in the front clamp so that its top
edge touches the guide fingers and is perfectly flush with the top
face of the drawer front
and the left edge is against the Spacer
.
! Board edges must be square.
