The fence controls the depth of the dovetail pins
by limiting the distance that the router travels. The
router stops when the router base hits the fence.
The fence must be adjusted parallel to the edge of
the vertical piece just like the template.
To adjust the fence:
1. Mount a 7 /
16
" O.D. guide bushing in your
router base. Measure the amount that the tem-
plate overlaps the vertical piece. Multiply that
number by two. For example, if the template
is offset from the edge of the vertical piece by
1 /
8
" and the thickness of the side piece is 1 /
2
",
then the overlap is 3 /
8
". So, 3 /
8
" x 2 is 3 /
4
".
2. Now, add 1 /
32
" to the distance you calculated
in step 1.
Explanation
Distance that the template overlaps the
vertical piece = A
Multiply A by 2 = B
Add 1 /
32
" to B = C
Add C to distance from edge of bush-
ing to edge of router base, D = E
E = distance from edge of template to
edge of fence
Example*
A = 3 /
8
"
3 /
8
" x 2 = B = 3 /
4
"
3 /
4
" + 1 /
32
" = C = 25 /
32
"
D = 3 1 /
4
"
25 /
32
" + 3 1 /

" = E = 4 1 /

"
Total = E = 4 1 /

"
Your Jig
A = ___"
A x 2 = B = ___"
B + 1 /
32
" = C = ___"
D = ___"
C + D = E = ___"
Total = E = ___"
3. Measure the distance from the edge of the
router base to the edge of the guide bushing
and add it to the distance you calculated in
step 2.
4. The distance calculated in step 3 is the dis-
tance that the fence should be back from the
template. Loosen the two fence lock knobs
and slide the fence into position. Ensure that
the fence is parallel to the front of the tem-
plate and tighten the two lock knobs.
Note: The procedure above is not affected by
changing the router bit vertical depth of cut.
When you’ve finished with all the calculations,
make a test run using some scrap wood to check
your positioning. Fine tune if necessary.
Figure 10 shows checking the alignment of the fence.

IMPORTANT
When you have come up with
a reliable number (E) for your
router, base, bushing, and wood
thickness combination, record
it here and keep it for future ref-
erence. E will be different for
different wood thicknesses.
