Position the template on top of
these two and clamp it down.
Set your router depth of cut to
the factory specified 12mm for
the SZ-14 and 15mm for the
SZ-20. Festool routers are easy
to adjust by zeroing the router
bit on top of the horizontal
work piece while the router is
in cutting position on top of
the template. Then you can
simply move the depth
indicator to the 12mm or
15mm mark, plunge the router
and you are ready to cut.
Be careful here.
Note that this
is NOT 12mm from the base of
the router, it is 12mm lower
than the bit when it is
positioned on top of the
horizontal work piece with the
router sitting in cutting
position on top of the
template.
If you use some other brand of
router be sure you can set the
depth of cut from a bit zeroed
on top of the work piece. Do
not try to set the bit depth of
cut with the router on the
bench as it will not be correct
and your joints will be way off.
Once the router bit depth is
set, make the cuts. Remove
the pieces and try the fit.
Usually the depth setting will
produce a properly tight fit,
but if it is off a bit lower the bit
to make it tighter and raise the
bit to loosen the joint fit.
Check how flush the joint is
when driven all the way home.
If the vertical piece (what will
normally be the side of your
drawer) stands proud of the
edge of the horizontal piece
(which normally will be the
front or back of your drawer),
then loosen the two holding
screws and turn each in/out
adjusting wheel to the same
mark in the + direction. Note
that the well engineered VS-
600 is calibrated so each mark
represents an 0.1mm
movement. If your edge
stands proud by 0.2mm, move
the wheels two marks and
tighten them down. If the
sides go in too far, move both
wheels in the – direction by
the proper amount.
It is a good idea to do one
more test cut if you needed to
adjust either the router bit
depth setting or the template
in/out setting. You only need
to do this once and that
template will forever be set to
produce your prefect drawer
no matter what length, width
or thickness of work pieces
you use (so long as the
thickness is within the range
specified for each template
and you continue to use the
same router bit).
When you have the fit you
want, save the pieces to use as
a router depth of cut gauge for
all subsequent uses of this
template.
The “right” fit is a matter of
personal taste. I like the joint
to go together with only a light
tapping with my hand or a
mallet. That will provide a
good bonding surface for the
glue and still show a tight,
artful joint. If the joint is
