3. 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 the table if you
need more precise measurements for the
location of the dovetail cuts.
4. 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 dovetail. 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
Figure 18 and 19.
5. Tighten the locking handles on the
horizontal fence to secure it in position. The
position of the horizontal fence will be used
as the basis for locating the vertical fence.
6. Loosen the locking handle on the vertical
fence.
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 inch 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 table are marked in
1/16” increments.
7. Line up the vertical fence with the horizontal
fence, then offset the vertical fence by
exactly half the pitch of the template. See
Figure 20.
8. This adjustment will cause the vertical work
piece to be slightly offset to the right of the
horizontal piece, thus ensuring the dovetails
will correspond when the two pieces are
assembled.
9. Tighten the locking handle on the vertical
fence.
There are a total of four fences on the DT45
Dovetailer – two vertical and two horizontal.
These allow two sets of workpieces to be cut at
the same time. If this is desired, position the
other two fences in the same manner as the first
two fences, remembering again to offset the
vertical fence by half the pitch.
