8-29 If the joint is loose, pull the pin board so that the angled
sides of the pins and sockets jam tight together
. The gap at the
bottom of the pins
is the amount you will have to move the
finger assembly out (toward you). Reset the finger assembly and
test again on the other end of this board.

scale setting on the pull-out or on one of the scale prints at the
end of this chapter. Very slight variations to the scale setting may
be necessary with different wood species or hardness. You can also
note this on the Quick Reference pull-out card.

outwards. (With luck you may not have used the fifth
board.)
8-32 Assemble the box, making sure the tail boards face the
proper way, i.e. tail boards inside face in

face out

. Provided you haven't already routed out the drawer
bottom grooves
, it doesn't matter which edge of any of the
boards are at the top or bottom, the box will still fit together i.e.
pin board “A” can be up either way.

8-27 Remove the test pin board from the jig and test it for fit in
one of the tail boards.
Make sure the outside faces outward on both pieces. A firm push fit
is perfect, perhaps a tap with the heel of your hand. Having to use
a mallet means the joint is too tight to take glue.
8-28 If it is too tight, move the finger assembly in (away from
you) by one division on the scale. If it is only a little tight, adjust
the scale by only half a division. Replace the same pin board back
in the jig, carefully aligned against the same side stop. Rout off
the sides of the pins and test it again for fit. Repeat as necessary
to get a good fit.
