that the back panel piece is the
same width as the top and bottom pieces but 1-1/2 inches
shorter than the side pieces.
Our prototype build helped us
see that the shelves themselves
were each slightly shorter than
the top and the bottom because
you need room to move them in
and out. Additionally, they needed
to be a full inch narrower than
the top and the bottom piece
because of the room that’s taken

plus a desired 1/4-inch reveal (or
set-back) to the front edge.
To avoid wasting material, we
cut a foot off each sheet of plywood to make them 4-by- 7 feet.
By doing this initial cut, we were
able to use the extra 1-by-4-foot
pieces to make shelves and
toe kicks. Had we started with
We used a clamp to hold our drill jig flush with
the bottom of the cabinet side panels.
