away from the operator by half the amount required.

If the tails fit in too far past the pins ends, set the

To make a box, repeat the procedure four times, ensuring
the drawer fronts, rears and sides are all rotated correctly in the
jig,
keeping the inside face i of the boards away from the jig .

Assemble the drawer. As with through dovetails, it doesn’t
matter which edge of any of the boards are at the top or bottom, the
drawer will still fit together e.g. pin board “A” can be up either way.

Hint: Increasing the Depth of Cut
(see page 40) This is
based on setting the eBush on 10. The depth of cut for each bit
can be increased slightly by turning the eBush to a lower number.
For example, if you turn the eBush from 10 to 9 you will have to
increase the depth of cut by 0.014" [0,36mm] for the 80-8 bit. If
you turn the eBush two increments to number 8 you will have to
increase the depth of cut by 0.028" [0,71mm] and so on.
