Here's a tall, floor-to-ceiling bookcase with the versatility to serve a variety of purposes
So, let's get started. 1. Cut the plywood to size. Begin by ripping the plywood lengthwise into 16" wide (or your preferred width) strips. Once the pieces are ripped, crosscut them to length as shown in the List of Materials (or to the lengths you prefer, in the case of a modified plan).
2. Cut the dadoes. Mark the positions of all dadoes on the insides of your two outside vertical panels (A & O). Follow the positions shown in the drawing or modify them as you see fit. Remember that (almost) all dadoes will be 3/4" wide and cut to a depth equal one-half the thickness of your plywood (or 3/8").
NOTE: The dadoes on the tops of the two sides (A & O) will form 3/8" x 3/8" rabbets - and the bottom dadoes on both sides of the vertical shelf divider (J) will only be 1/4" deep.
Carefully line-up the marks you made on the edges of your plywood with your Dado Blade. Start by crosscutting your dadoes with one edge flat against your Miter Gauge. A Miter Gauge Extension Face or Cross-Cut Sliding Table and Auxiliary Table will provide additional workpiece support and precision when making these cuts.
This process can be a bit tricky since furniture grade oak plywood has a thin veneer on each outside surface that is highly susceptible to splintering if it's not cut properly. There are two ways to avoid this. One way is to make your dado cuts in two passes….the first just a little over 1/32" deep to “score” the veneered surface before cutting your dado to its final depth. The second way is to cover the entire length of your dado cut with a piece of masking tape before making your cut (be sure to set your blade cut depth just a “shade” deeper to compensate for the thickness of the tape). If you're using this second procedure, once your cut's been made, slowly and carefully remove the tape.
Set your MARK V's Speed Dial to “R” and make your cuts, pushing your workpieces slowly over the dado blade, almost at a snail's pace, giving the blade ample time to make the cuts.
Once you've cut the dadoes on the sides (A & O), go ahead and cut the remaining dadoes on the shelf divider (K) and fixed shelves G & N). Next, mark the dadoes on the vertical shelf divider (J). NOTE: Since the bottom dadoes on this piece will be adjacent to each other, adjust your depth-of-cut to make them just 1/4" deep. Mark and cut the single dado in the center of the top (B)…but NOT the ones on the ends.
