Place your two side pieces together and mark a line at 18 1/2” from the bottom of both pieces. Now attach your bottom flush with the bottom of the two side and the top with the bottom of the piece at the 18 1/2” mark.

Make sure that the box is square and then mark a line on the top and bottom pieces at 6 1/4” from the outside edge. This will be from the side with the dados. You can now install the divider with the inside edge at the 6 1/4” mark. Make sure to install it with the previously marked bottom end pointing towards the bottom of the box.

Once that’s installed measure and mark lines at 7 1/2” and 11” from the bottom edge of the box. These lines will be marked on the right side of the box and on the divider. With the chamfers pointed towards the top, install the shelf with the cut slots. Alight the bottom of this shelf at the 7 1/2” mark and attach with pocket hole screws.

After that, install the top shelf with bottom of the shelf at the 11” mark. If you place the shelf so that the pocket holes are on the top side it will give you plenty of room for your drill.

Lay the drill station on its face and install the top half of the back with the 45 degree angle in the correct position.
