I ended up making a number of practice cuts. The first revealed that I hadn't tightened the screws on the edge guide enough. The second revealed that the design of the edge guide provided very little support at the end of a board, because of the cut-out for the router bit. In the "Getting Started in Woodworking" video, they had screwed a piece of hardwood to the edge-guide, to provide a continuous -- and longer -- bearing surface. I may do that myself, some day, but I didn't have the materials at hand, so I clamped some 2x4 scrap to the end of each board, to provide a continuous bearing surface past the ends. The two grooves in the long stretchers and the side groove in the short stretchers have identical layout. I made practice cuts in scrap until I had the edge guide set correctly, then I cut them all with that one setting. The bottom groove of the short stretchers uses a different setup, so it was back to the scrap, before cutting them.
This book is a solid book and much more than I would of imagined. I was thinking ok 40 plans cool. They go into detail on each plan. They give accurate measurements, pictures, times for each stage of a project, list of tools, wood, and anything else you need to complete each project. This book goes so far to even show you how to setup your own project and draft it and gives you a list of what you might need to draft out a project. I would say this book is good for anyone from Novice to Advanced. It is just a great read as well.
To develop the material, we editors asked ourselves—and dozens of top woodworkers—what’s likely to go wrong at each stage of a project. We really dug deep to make sure we didn’t just repeat the types of advice you see in the average magazine. We ended up with a list of more than 500 problems covering everything from design and layout, to stock preparation, joinery, finishing and more. Then, we reached out to top woodworkers around the country for their solutions. The result was a 320-page book filled with some of the best advice you could ever find from more than 75 master craftsmen, including Marc Adams, Mike Dunbar, Graham Blackburn, Toshio Odate, David Marks, Frank Klausz and Lonnie Bird.
In the "Getting Started with Woodworking" video, the holes through the 4x4's were drilled from the back. That is, they start on the side opposite the precisely-positioned mark, and drill through to hit it. If they can do this, more power to them, but I can't drill through 3-1/2" of wood to emerge at a precise mark without a drill press - and not always then.
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.
This table top is also made from the hardest wood out of any manufacturer we reviewed: oak. In fairness, this can be both a blessing and a curse. The oak wood is extremely durable and noted for its lack of a porous nature. This means the top can withstand plenty of abuse from tool and workpieces. Moreover, you will not have to worry about liquids like lacquers and stains from being absorbed into the top. That said, the hard oak can also do a number on tool sharpness, dulling them prematurely if they are not carefully handled.
