Put the upper panel of MDF on your glue-up surface, bottom side up. Put the bottom panel of MDF on your other surface, bottom side down. (The panel with the holes drilled in it is the bottom panel, and the side that has the your layout diagram on it is the bottom side.) Chuck up in your drill the appropriate driver bit for the screws your using. Make sure you have a freshly-charged battery, and crank the speed down and the torque way down. You don't want to over-tighten the screws, MDF strips easily.
Of course, I, on the other hand, with my Ikea oak countertop, probable went overboard in the other direction. Since I needed to trim the countertop to width,I figured I'd take off a couple of 1/2" strips to use for edging the MDF. I clamped the countertop to my bench base, and used the long cutting guide. I'd asked around for advice on cutting this large a piece of oak, and was told to try a Freud Diablo 40-tooth blade in my circular saw. I found one at my local home center, at a reasonable price, and it worked very well.
The hacksaw will often damage the last thread when it cuts. Running a nut off the end will fix this. You'll have to run the nut all the way down from the other end. This doesn't take long, if you chuck up the rod in your drill and let it do the work. Hold the rod vertically, with the drill pointing down, and just hold on to the nut enough to keep it from spinning.
The next day, cut it flush. Use a block plane to ensure it truly is flush. This will be the top of the bottom layer of the bench top, so gouges aren't a problem. (Wiping up glue with a damp cloth can lead to stains and finishes applying unevenly. That won't be a problem here, either.) But bulges and bumps are a problem - they will keep the two layers of the top from matching up evenly.
I find furniture takes on new meaning when separated from the sterility of an art museum (such as the Philadelphia Museum of Art’s American Wing. Maybe that’s why I prefer the museum’s period rooms). Jeffrey P. Greene’s book is perhaps my favorite of recent period woodworking texts for its ambition and helpful exploded diagrams of furniture in its appendix.
I decided to finish the top with a number of coats of Danish oil, followed by a coat of wax. I applied the first coat of oil in the usual manner, making sure to cover the edges, and down the holes. I applied a coat oil to the top side of the shelf, as well. Wipe it on, let it sit wet for half-an-hour, then rub it off. Wait a day or two, add a second coat, and then again for a third.
These sorts of things are usually glued and screwed, but it's actually the glue that holds them together - the screws just hold everything tight while the glue cures. Screwing into hardboard or 1/4" ply is an exercise in futility, so I just used glue, and used my two 4x4's as long clamps. It would have been a bit easier, if I'd done this before I'd rough-cut the 4x4's, but it worked out.
Having done all this, I'm not sure I'd do it this way again. It might well be faster to layout the positions with compass and straightedge directly onto the top. Either way, you'll want to use a scribe rather than a pencil. Scribe lines are hard to see, and impossible to photograph, but the scribe and compass points click into them, allowing a precision that pencils simply cannot match.
We want to make these pieces square, and of identical length. Square is a matter of making sure the saw blade is square and that the cutting guide is square. The trick to getting the pieces of the same length is to clamp them together and to cut them all at once. For the 4x4's, that means making a rough cut in each first, so we have four pieces, each 3-4" longer than we need, from which we'll get our four legs.

With a pencil and a protractor, divide the larger disc into 30-degree wedges to create 12 center lines for the bottle indents. Center and trace the smaller disc on top of the larger disc. Next, with a drill press, drill 3/8-in.-deep holes on the 12 center lines with the 1-7/8-in. Forstner bit, spacing them between the disc’s outer edge and the traced circle. Next, divide the smaller disc into 60-degree wedges and drill six more 3/8-in.-deep holes with the Forstner bit.
Being a lover of Japanese design and tools, I’m embarrassed to say I only picked this book up in the last year. I was anticipating a straightforward, almost encyclopaedic, approach documenting the history and use of most Japanese woodworking tools. I got that, but also so much more. The stories Odate tells of his youth and apprenticeship are truly jaw-dropping, and reveal as much about working wood in Japan as what life in a fascinating and secluded Pacific country was like when he was young. I was five minutes into this book, and I guess I had an astonished look on my face, when my wife politely asked how I was enjoying the book. I looked up in bewilderment, paused for about five seconds, and said “It would take me an hour to explain what I’ve learned in the last five minutes,” and went on reading. Even though this book has been around for decades, it’s worth reading today.
1. Cabinet Making and Millwork by John L. Feirer. I read this book cover to cover when I first got into woodworking, and its still my number one reference book when researching a project or technique. I believe it was intended as a textbook for a high school shop class, so it's laid out in great 101 style. It includes descriptions of everything from how sandpaper is made to best practices for shop math, and provides details for both hand and power tools.
Drill four 5/8-in.-dia. 1/2-in.-deep holes on the large disc?inside the traced circle?then use 5/8-in. dowel centers to transfer the hole locations to the underside of the small disc. Drill four 1/2-in.-deep holes on the underside of the small disc and a 1/2-in.-deep hole in the center of the top for the dowel handle. Glue in the dowels to join the discs, and glue in the handle. We drilled a wood ball for a handle knob, but a screw-on ceramic knob also provides a comfortable, attractive grip.
