Box Joint Procedures - 3/4"
B
11-9 Insert the right frame pin in the
No.1 BOX JOINTS
hole
A
and the left frame pin in the matching slot, then latch the frame.
Put the short end of the stop rod into the
3/8"
BJ STOP SET
hole.
Slide the sidestop to lightly touch the rod
B
and tighten the stop.
Store the stop rod in the ¾" slot.
11-13
Adjust the bit to the center of the line.
Double check
that the bit still rotates freely.
IMPORTANT: Bit height determines
the flushness of the joint, so set your bit properly the first time.
Adjustments for flushness are at the end of the chapter.
11-12 Place the end of a pin board on the template and pencil
a line on the tail board.
11-10 Clamp socket board 1 flush on the template
B
with the
side edge against the sidestop
A
.
Always keep the same side
edge of the board to the sidestop when routing box joints
C
.
If board width is only slightly narrower than the chart width, center
the board over the template, clamp in place and move sidestop to
touch the board.
11-11 Position a backer board " [1.5mm] away from the
edge of the socket board
A
. This prevents the backer board from
interfering with the sidestop when the frame is repositioned in
the second step. The backer board stays in place for the complete
procedure.
Note: Clamp removed for clarity.
11-8 With the router unplugged, install the supplied ⅜" Leigh
143-500 bit. For cleaner routing use the optional ⅜" Leigh
173-500 (HSS) or 173-500C (solid carbide) spiral upcut bit,
available at leighjigs.com. Make sure the bit spins freely before
connecting the power.
