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.

8-30

Once the correct fit is achieved, mark the final

d

TD PINS

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.

8-31

Rout all four ends of the pin boards, keeping the outside

face

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

i

; pin boards outside

face

out

o

. 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.

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.
