paint grade work, I will shoot about
three nails evenly spaced through
the face frame and into each shelf
just for extra hold until the glue
dries. After attaching the face, cut
the back out of^1 / 4 " plywood then
glue and staple it on.Mount the Hinges
Mounting the hinges is critical to
a good-fi tting door. If you’ve never
done this before, it’s a good idea
to make a working mockup to test
placement. To mount the hinges on
the case, you'll need to shim the top
with a^1 / 2 " block, and the bottom
with a^3 / 4 ". I use scrap pieces and
cut blocks about 10" x 7" and place
them directly in the corners where14-15 I mark, check, and recheck
mounting the hardware and drilling
through-holes for the pivot pins.
16 Attach the top part of the upper
pivot hinge to the header, paying par-
ticlar attention to alignment and the
offsets indicated in the directions.
17 Do the same thing with the fl oor

attach it to the concrete here, and
I also drilled out a little extra room
where the pivot point attaches.14 15

the hinges will mount. Glue and
nail them on and then install your
hinges as shown in the diagram
at left (follow the manufacturers
instructions). Pay attention to
the individual components as one
blade of the pivot hinge is threaded
and must be installed on top of
your case. You will drill a^5 / 8 " hole
through the top and into your case
to allow access to the Allen screw
that threads into this blade and acts
as the upper pivot pin.Install the Door
First start your Allen screw through
the top hinge and add the supplied
washers to the threshold hinge pin.
