the drill.

Laying out the desired position of your dowels is important before using the jig. There are numerous configurations of hole
spacing that can be used depending on the stock thickness and desired location.
Note: Your 08350 JessEm Dowelling Jig comes
standard with a 3/8” drill bit and bushings

Setting the Drill Bit Depth Collar:
Using the matching stop collar for the drill bit you are using, screw
the ¼”-20 set screw into the stop collar. Now slide the stop collar
over the drill bit and with the 1/8” hex key snug the set screw to
keep the collar in position. (See Figure # 1)
** Note: Locate the set screw on the largest portion of the drill bit
not in one of the chip removal flutes. (See Figure # 1)
Figure 2
Figure 3
The first joint we are going to drill has 3 rows of dowels. We are
spacing our jig ½” from the edge. Clamp the jig to your board in
this position. (See Figure #3)
Figure 4
We want three (3) holes in this first row. One (1) in the center and
one (1) in each outside hole. (See Figure # 5)
With the first row drilled, adjust the jig to the 7/8” position.
Note: Do not unclamp the Jig from your board. (See Figure
#6)
MULTIPLE ROW DOWEL JOINT
Insert the drill bit into the corresponding drill bushing and measure
the amount the drill bit protrudes (See Figure # 2). The drill bit
should be deep enough to accomodate half the dowel you are
using. For thinner stock, ensure the dowel pin does not break
through your material and compensate by drilling deeper on the
corresponding piece.
We have predetermined that we want the first row of dowels
spaced 3/8" of an inch in from the edge. Loosen the adjustment
knob and adjust the jig to the 3/8" position. (See Figure # 4)

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
each row. These are the same settings as drilled in the first
board plus ¼”. This will give the ¼” offset.

The next joint we are showing is the joining of two boards
to make a larger panel. Mark the lines on the board
where you would like to place the dowels and clamp the
jig centreline to the board on this line. (See Figure #14)
With all of the holes drilled in the first board, clamp this
board to the mating board with the edges lined up and install the
dowels in the holes previously drilled. Using the alignment slot in the
jig, you can align the jig on the mating board using the dowels in the
first board and clamp in this position. (See Figure #16)
All of the holes are now drilled. (See Figure #18)

FLUSH JOINING BOARDS
With the drilling completed in the second board, all we
need to do is test fit the joint. (See Figure # 13)
Drill a hole in the centre bushing and repeat for all of the
holes.
Figure 14
Now, drill a hole in the centre bushing. (See Figure #15)

Test fit the joint. (See Figure #19)
We are now going to join a shelf board to the mating piece.
We marked a centreline on the shelf and aligned and
clamped the jig in this position. (See Figure #20)
Drill a hole in the centre bushing. (See Figure #21)
We are using the indexing pin and the centre hole previously
drilled to position the jig for the third hole. (See Figure #23)

Joining a Shelfboard
Drill the third hole in the far right bushing. (See Figure #24)
We are using the indexing pin in the centre hole previously
drilled to position the jig for the second hole. (See Figure #22)
We are going to drill a hole in the far left bushing.

The distance from the front edge of the jig is 2” from the
centre of the bushings. Mark a line where you want the
dowels and also 2” from this point. Clamp the shelf board
on the 2” line.

The shelf board is now complete. (See Figure #25)
Install dowels in the shelf board and using the alignment
slot, align and clamp the jig in position. (See Figure #26)
Drill using the centre bushing and repeat for each location.
(CAUTION: ADJUST THE DRILL BIT DEPTH COLLAR
TO ENSURE NOT TO DRILL COMPLETELY THROUGH
YOUR BOARD. (See Figure 27, 28 and 29)
With the holes drilled, test fit the joint. (See Figure #30)
