NOTE: Make sure locking handles (A & B,
Figure 19) will not interfere with the headstock
during operation.
5. Continue to check the spacing by sliding the
headstock across, until the dovetail cuts will
be distributed evenly across the width of the
workpiece. NOTE: This is an approximate
method of determining by eye where to
place the workpiece. A scale in inches and
millimeters is mounted to both horizontal
and vertical tables, if you need more precise
measurements for the location of the
dovetail cuts.
6. Again, make sure the locking handles on the
horizontal fence (A & B, Figure 19) are
tightened. The position of the horizontal
fence will now be used as the basis for
locating the vertical fence.
7. Loosen the locking handle on the vertical
fence.
8. As noted, the position of the horizontal
fence will affect the position of the vertical
fence. Therefore, if you are making a drawer
that has a bottom groove, the vertical fence
should be set so that the bottom groove in
the drawer piece to be tenoned will go
through the center of a tail. That means the
bottom groove of the mortised piece will go
through the center of a mortise. This will
prevent the groove from being visible on the
outside of the assembled drawer. See
Figures 20 and 21.
Important: To make proper dovetail cuts, the
two fences must always be offset from each
other by half the pitch of the template bar. That
is, offset 1/2” when using the one-inch template;
3/4” when using the 1-1/2 template; 1” when
using the two-inch template, and 1-1/4” when
using the 2-1/2 inch template. The measuring
scales on the horizontal and vertical tables are
marked in 1/16” increments and millimeters.
9. Line up the vertical fence with the horizontal
fence, then offset the vertical fence by
exactly half the pitch of the template bar.
See Figure 22.
10. This adjustment will cause the vertical work
piece to be slightly offset to the right of the
horizontal piece (as viewed from front of
machine), thus ensuring the dovetails will
correspond when the two pieces are
assembled.
11. Tighten the locking handle on the vertical
fence.
