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.

A better solution would have been to route a rabbet into the side, so that the added strip always had thickness. The way I did it means that the strip I glued in is very narrow, and hence very weak, at a certain point. In this case, that's not a problem, because it's going to be sitting under the countertop layer. I also noticed that because I had only clamped the strip down, and not into the edge, there was a noticeable glue gap where the strip butted up against the MDF. Again, in this application it isn't visible. But if I was doing something like this on the top of a table, I'd make sure to cut a clean rabbet, and to clamp both down and in.
In each Practical Woodworking Class, the daily mix consists of intensive lecture, demonstration, and student practice lab time.  Lecture periods are interactive, informative, and intensive but are also an enjoyable experience.  Generally, each joinery and fabrication process is demonstrated in several ways to reach or achieve the same results.  For example, processes are first demonstrated with the use of hand tools. Next, the same joint or procedure is done with simple hand held power tools (such as the router). Then, the entire process is demonstrated with stationary equipment such as the table saw, drill press, and mortiser. Students choose whichever production method works best for them and is in keeping with their plan to equip a home workshop and/or around their existing home tooling.
Well, not these plans. You have the option of building a very functional and spacious lean-to shed on different foundations. Your foundation choices are: concrete slab, a wooden floor supported by concrete piers, or a wooden floor supported by skids. That lost option also means that your lean-to could be mobile as well so you won’t have to decide where you want to permanently put it.

With the top laying on the floor, bottom side up, the next step is to flip the base upside down, and attach it to the top. I followed Asa Christiana's design, in using s-clips. When I stopped by my local Woodcraft, though, they only had two packages of ten, so I didn't use as many as I would have, otherwise. For the top I put four on each side and two on each end. For the shelf I put three on each side and two on each end. If it turns out that I need more, I can always add more.
Can't say enough about the team at Post Woodworking, Inc., from Karen in the office to the team that... put up this beauty starting at 7AM and were done before lunch, Kyle, Aaron and Billy. After what sounded like a late night at the shop the night prior, they were still on site bright and early as promised and still energized and ready to show their pride in their work. Couldn't be more happy with our 14' x 20' Cohasset. See More

After I left the magazine for a new job, I did all of my woodworking in my small two-car garage, but it was a struggle. Power, lighting, and temperature control were limited. And because I shared space with our cars I was always moving machines around, often while in the middle of a project. On top of that, my tool and machine collection had long since eclipsed the space. For all these reasons, fixing up the garage wasn’t an option. My finished basement is a family room, so it was out, too. An addition to the home or a stand-alone building would have been too expensive. I had to find a better path to a shop.
