the same thickness) underneath the clamp bar at
the opposite end to ensure an even grip on the
wood and to avoid distorting the bars.
Setting the Template Position
–
Unlock the two template securing screws and
position the template so that the tips of the
fingers sit 3mm back from the edge of the
vertically mounted timber.
–
Lock the template into position using the two
template securing screws.
Setting the Backstop
The distance the backstop needs to be
positioned from the front of the template fingers
depends on the size of router base fitted to your
router,
The formula to calculate this is:-
–
Set a micrometer or Vernier caliper to the
calculated depth and adjust the backstop as
shown (next page).
–
Lock into place using the backstop locking
screws. It is not essential that this setting is exact
at this stage as final adjustments can be made
later on.
–
Ensure that the template and back stop stay
parallel with the front edge of the jig during this
setting procedure.
Setting the Cutter Depth
–
Fit the bearing guided router bit securely into
the router collet.
–
Adjust the cutter depth, until the bottom of the
router bit protrudes10-11 mm below the template
fingers.
–
You may need to fit a packing piece between the
template and the timber to ensure good contact
between the bearing and the slots in the template.
–
The cutting depth is critical to the final fit of the
joint, with as little as 0.5mm change in depth
making all the difference.
