We are drilling two (2) holes here. One (1) hole to the left
and right of the centre hole. (See Figure #7)
Now adjust the jig to the 1-3/8” position. (See Figure
#8)
We are now drilling a three (3) hole pattern as done in the
first row.
The holes in the first board are now complete.
We
follow the same procedure to drill the holes in the
mating piece. In this
joint you woulld like the first board to be
stepped back ¼”. Set the jig to 5/8”, 1-
1/8” and 1-5/8” for
ea
ch row. These are the same settings as drilled in the first
board plus ¼”. This will give the
¼” offset.
