Making Your Perfect
Drawer Using
Through Dovetail
Joints
Through dovetails are
considerably more
sophisticated and complicated
joints to cut than are half blind
dovetails. The male fan shape
has to be cut by a dovetail
shaped router bit guided by a
template with straight fingers
with the work piece held
vertically.
The female recesses are cut
with the work piece held
vertically using a straight
router bit guided by a
template with angled fingers.
To fit, the angle on the dovetail
bit and the angle on the pin
template fingers must be
exactly the same. Also, the
spacing must be exactly the
same.
Fortunately, the superbly
engineered Festool VS-600
does most of the work for you
once you prep your work
pieces as described above and
determine the correct sizes to
cut your component parts.
As discussed earlier, I strongly
recommend the use of Festool
router bits and guide bushings
when cutting through
dovetails on this jig.
Length
- Determining the
correct lengths for your perfect
drawer sides, front and back is
easy. Just cut them to the
exact length you want for the
outside width of the drawer
and for its depth, front to back.
Height - centered
dovetails look best
–
Calculating the correct height
for your drawer to make sure
your dovetails are properly
centered is a bit more
involved.
You want half pins at the
upper and lower sides of your
drawer.
This drawer has the dovetail
shaped male pieces shown
from the front, normally they
would show from the side
.
These are the outboard most
sides of the female recess at
the top and the bottom of the
drawer no matter how many
female recesses there are in the
drawer side. If you get an
equal sized half pin top and
bottom, you will automatically
have evenly spaced, centered
dovetails that will look good
and hold tight for generations.
The trick is understanding the
template spacing, the side
offset and the maximum
diameter of the dovetail cutter
used to cut the male fan
shapes.
These male fan shapes or tails
are usually cut in the
sides
of
the drawer using the template
SZO-14-S or SZO-20-S. The
female recesses and pins are
usually cut in the front and
back of the drawer using
template SZO-14-Z or SZO-20-
Z.
