My next step is to take the rough cut oak plywood and cut
it to finished size plus do any other machining needed. To start I take the rip blade off the saw and
replace it with the blade I use for cutting plywood to size. The surface layer of oak hardwood veneer on
this plywood is very thin, less than 4 thousandths of an inch thick. Being this thin it is very susceptible to
splintering when being cross cut. A good
blade designed for the task helps reduce the problem.
My first set of pieces to work on is the sides cutting
them to width. I set the fence slightly
wider than the finished side is wide so I can flip the piece and recut the
factory edge. That edge is generally
straight and square but you can count on it being chewed up a little bit in
shipping so a recut gives me a clean straight edge.
Ripping Sides |
After ripping both sides to width I changed the blade to
two 1/8” thick dado blades so I could cut a rabbit in each side to house the
back. Because the back of the cabinet is
only 3/16” thick I needed to bury 1/16” of the blades width in the fence.
Setup for Cutting Rabbit in Side |
Running the side through this setup gave me the recess
needed for the back.

Next is to cut the pieces to length. Because of the size of the side (21” wide
& 6’ long) it’s too wide for the chop saw and too long to use the table saw
fence. For cases like this I built a
cutting sled that accurately holds the piece in place and slides across the
table saw making a square clean cut.
Using Sled to Crosscut Side to Length |
The last bit of cutting is for the toe kick. I used a jig saw for this cut. Process is to put down some masking tape to
prevent splintering of the oak veneer, layout the cut and carefully saw. There are a couple of considerations for a
clean cut. First, is to install a
non-scuff plastic base on the saw and second is to use a good blade.
Layout for Toe Kick and Jigsaw Pieces for Cut |
The blade makes a huge difference. Here I used one designed for clean cuts in
wood. What makes it different is that
the blade and teeth are ground versus being stamped.

The end result is a splinter free clean cut.
Completed Toe Kick Cutout |
The last operation on the sides is to drill a series of
pocket holes. These are angled holes
drilled with a jig for with screws will hold the cabinet together. The ones here in the sides will hold the
face frame on.

Oak Edging Strips Being Sanded to Thickness |
With the sides done I started on the top, bottom, and
fixed shelves. They are all the same
size so it makes sense to do one setup on the table saw and cut them one after
another. However, there is one shelf
that while the same size has a little bit different construction. It’s front raw plywood edge will be exposed
so I needed to cover it with a ¼” solid oak strip. The others will have their plywood edge
covered with an oak face frame so they do not need the facing.
To start I ran the slightly oversize ¼” thick strips
through the thickness sander to get them all to a consistent ¼” thickness then
turned them 90 degrees and brought the width down to ¾”.
With that done I took one of the strips cut it slightly
longer than the shelf then glued and nailed it to the shelf edge.
Setup to Attach Oak Edging Strip to Fixed Shelf |
To nail the strip on I use a pneumatic pin nail gun that
shoots very thin pins. They are 23 gauge
which works out to less the three hundredths of an inch thick. Being that thin they are just about invisible
in this application.
Pin Nails and Penny |
I start the strip about 1/32” back from the edge of the
plywood so when I make the first cut slightly oversize for length there won’t
be a conflict with the fence. The piece
is then flipped and the opposite end is cut to get the final width. In this
picture there is one of the pin nails about an inch back from the end.
Applied Oak Strip |
The oak strips are ¾” wide and the ¾” plywood is really
“about” 1/32” thinner. I say about
because the thickness varies. The result
is that I have a little lip where the strip overhangs the plywood. I don’t want that lip, I want a flush
surface. My method to achieve this is to
use a small hand plane to get really close then finish off with a hand
scraper.
Once I am finished the edging blends in with the plywood
very well.

Hand Router & Edged Oak Strip |
The last step on this shelf before cutting to final size
is to round over the oak facing strip. I
don’t want a hard sharp edge here so to soften will route a 1/8” radius on it
using a small handheld router.
With this done I am ready to cut the top, bottom and
fixed shelves to their final length and width.
