Keep the test tail board that fits well, and mark it with
the number of the bit you used to rout it. For quick set-up next
time, clamp this tail board in the jig as a depth-of-cut gauge

to
show how far to lower the bit. Better yet, measure the bit projec-
tion from the end of the guidebush

or guidebush flange

and
record this for fast set-ups in future.

When you have the proper tightness of fit, check the
flushness. The tails should be under flush to the pins by no more
than
1
⁄
64
"[0,3mm] to allow for cleanup (exaggerated here). Any
concentricity errors in the collet and guidebush on different routers
will affect this tolerance.

the jig,
keeping the inside face

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.
