overly tight and requires
heavy blows to get it together
then the glue will either get
scraped off when you
assemble, or will get trapped
in the bottom of the female
recesses and lock the joint
open, or you will break
something during assembly.
While many of my colleagues
will disagree with me on this
point, with today’s glues I
think it is better to error on the
side of being too loose than too
tight for half blind dovetails.
The one time adjustment for
the SZO-14 and SZO-20
through dovetail template sets
is very much the same. You
will, however, have to cut the
two test pieces separately. The
template with the straight
fingers will cut the male fan
shaped tails using the
specified dovetail cutter and
the template with the angled
fingers will cut the female
recesses and surrounding pins
with the specified straight
cutter.
Be sure you place a scrap piece
under the top clamp bar that is
at least 5mm thicker than your
horizontally mounted test
work piece to avoid cutting
into the VS-600!
As before, once you make your
test cuts put the two pieces
together and observe the fit.
If the edge of what would
normally be your drawer side
(the piece cut with the straight
fingered template) stands
proud from the end of your
drawer front/back (the piece
you cut with the angled finger
template), loosen the securing
screws and turn the two
in/out adjustment wheels to
create a perfectly flush joint.
If the ends of one or the other
of the two pieces protrude
beyond the outside edge of the
joint, reduce the depth of cut
setting until they are both
exactly flush. Since you have
to adjust the depth of cut for
both templates and the in/out
on one, plan on doing a couple
of test cuts.
Remember, you are only going
to do this once for each
through dovetail template set
so take your time and do it
right.
Once you have a correct fitting
joint the template in/out
setting will be correct for all
further use of that template.
Save BOTH test pieces to use
in setting the correct router bit
depth whenever you use this
template set in the future.
