aim being to create a small cut line along the face of the
board, see diagram below.
15. Moving from left to right cut the rest of the joint,
making sure to follow the contour of the comb, when
complete ensure that the cutter is not in contact with
the workpiece, switch off the router, let the cutter come
to a complete stop before removing from the jig.
16. Check that the workpiece has been cut evenly and
that the cut line follows that of the contour of the comb,
any bumps that do not follow the contour of the comb
will effect how the joint goes together. If there are any
problems re-cut with the router to remove. It is important
that the guide bush travels all the way back into the
recess shape and follows the shape curved contour of
the comb bar, see fig 53.

17. With the comb bar is removed it shows the two
boards held in the jig having been cut in the offset
position, see fig 54-55.

18. Remove the two boards from the jig and assemble
them.
19. Check how the two boards fit together, it is now
possible to adjust the tightness of the joint fit, this will
require a small amount of adjustment to the cutter
depth ,and is best achieved using the fine height
adjuster on the router. This adjustment affects both
parts of the joint as they are cut at the same time. The
density of material that is being used will play a part in
this as a hard brittle wood like, oak will not compress
when pushed together, unlike pine which will compress
when the boards are assembled.
If the resulting joint is too loose when fitted
together then lower the depth of the router cutter.
If the resulting test joint is too tight then raise the
cutter height, this will need doing carefully with
small adjustments as it affects both parts.
20. The other important aim of the test fit of the joint
is to check how the two boards meet on the outer face.
This can be adjusted by moving the comb bar forward
or back on the jig.
