I marked out the one hole location, drilled a shallow 1/16" hole into the top. I then put a 1/16" bit through the hole in my template and into the hole I had just drilled. I lined up the template, and drilled a second hole, then put another bit through that. From then on, I worked entirely from the template. With two bits through the holes pinning the template in place, the other holes in the template would be precisely located (or so the theory goes) on a 4x4" grid.
The Joint Book contains easy-to-follow step-by-step instructions for creating edge and scarf joints, lapped and housed joints, mortise and tenon joints, miters and bevels, dovetails, dowels and biscuits, and provides detailed descriptions of fasteners, hardware, and knockdown joints. This book is the perfect companion for any woodworker interested in improving their joint-making skills.”

Put the countertop on the base, put the MDF on top of the countertop, and line up the marks you drew on each end of the MDF with the countertop below it. When you have it lined up, clamp things down, and route the edge of the MDF using a 1-1/2" or longer flush-trim bit, with the depth adjusted so the bearing rides on the countertop. I clamped a couple of scraps of doubled MDF at each end to give the router base something extra to ride on at the ends.
With my second attempt at edge guides, I made the other rough-cut. On this, the edge guide worked fine, but the end of the cuts revealed that the saw blade wasn't quite square. So I adjusted the blade, clamped all four legs together, and made what would be the first final cut, if it came out clean enough. It didn't. I'd let the saw drift a bit away from the guide edge. So I adjusted the saw, moving the guide back half an inch, and tried again. the rough-cut parts were a couple of inches longer than they needed to be, so I had room to work with,. It's only the final cut at the other end that you only have one chance at.

Even in today’s world of electric machinery, when most people were asked to name a woodworking tool, planes and scrapers would probably be at the top of the list. They are as useful now as they were years ago but, because of their electrified cousins, they are often overlooked in favour of a faster option. In this compre­hensive book, John English explains what each type of plane is for, how to set it up for optimal performance and how to use it. The text is thorough and the photos are informative. All in all, this is a good read for a beginning or intermediate woodworker. Or a woodworker who simply never gave hand planes and scrapers a fair shake.
I mocked up the two scenarios, and determined that with the plate inside the stretcher the vise would have a reach of 8 inches, and with it outside the stretcher it would have a reach of 9 inches. I decided that 8 inches was enough, and that the extra inch wasn't worth the extra effort. With the end vise mounted like this, the right edge of the top would have no overhang.
Of course, few benches can be ideal, and this one does have some drawbacks. That being said, most of the disadvantages of this bench are minor annoyances rather than deal breakers. For instance, this bench does not include any kind of storage whatsoever. Though, it does have the option of adding numerous additional features like a storage area. Still, for the bench, you would expect a drawer at the very least, maybe a shelf below the main table area.
