The original design had a height of 35-1/8". Their two-layer top was 1-1/2" thick, so their legs were 33-5/8" long. I want a height of 35", but I'm using a top that's 3" thick. My basement floor is anything but level, so I'm using levelers that are adjustable from 3/4" to 1-1/2". In other words, I want legs that are around 31-3/4" long. (If you're not using levelers, your legs need precise lengths. The levelers give about 3/4" of adjustment, so precision is less necessary.
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.
The reason I'd cut out the rectangles in the vise support was that I'd intended to put a benchdog hole through each, and I wanted the thickness of the top to be the same for all of the benchdog holes. Where I messed up was in not cutting out the ends, between the bolt tabs. I'd intended to put a benchdog hole through there, as well, but I'd forgotten to cut out the segments prior to glue0up.
First, cut one long edge. Second, cut a short edge, making sure it's square to the long edge you just cut. Clamp both pieces of the edging you'll be using along the long edge you've cut, and measure the width of the base plus 1/4-1/2", mark that, and then lay out a line through the mark that is square to the end you've cut, then cut along the line. Finally, cut the remaining short edge square to both long edges. (The length of the top doesn't need to precisely match anything, so we don't need to bother with clamping the trim before measuring.)
Mine is similar but a bit more robust. The top is a sandwich, two 18mm sheets of WBP ply with an 18mm mdf filling. The legs are mortise and tenoned together, the ends glued and pegged, the stretchers are joined with long bolts so it comes apart. I stiffened it by adding a very closely fitted cabinet underneath (it had to go in dead square) and it is now absolutely rock solid.
“The Wheelwright’s Shop” by George Sturt (Cambridge UP). Here is the real deal. At the turn of the 19th century, a guy comes back from college when his father falls ill and can no longer manage the old family wheelwright business alone. He realizes that he has stepped into a vanishing world of “kindly feeling” when the “grain in the wood told secrets to men.” Thanks to Sturt, the old English way with wood is still alive in the pages of this remarkable book.
2 - use a plunge router with a bottom bearing cuter bit such as this from rockler: .... I thought to use the short one as I plunge it directly downward in the centre of the hole until the bearing reaches within the tabletop hole. I suppose one could use a long one, but the stubbiness seemed more practical (the big bearing ensured accuracy?)

The end vise will have both jaws made out of 1-1/2" thick oak. The front vise has its moving jaw made of 1-1/2" oak, but uses the edge of the bench as its stationary jaw. So while for the end vise, if we mount it lower, we can make both the jaws deeper to compensate, for the front vise we cannot, so we want it mounted as close to the edge of the bench as possible.
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.

For those who would like to have the benefit of a woodworker’s extensive experience with hand tools, this is the book to own. Crammed with practical information, it is the next best thing to looking over a craftsman’s shoulder as he works with his tools, asking questions and getting straight answers in plain language, seeing how each tool is held and manipulated to get the best work out of it. From bit brace, chisel, and mallet to saws, specialized planes, drawknife, and spokeshave, Aldren Watson describes in detail the actions of the tools basic to good woodworking. All the procedures are explicitly illustrated with handsome line drawings, and an appendix gives plans and dimensions for making a workbench and other necessary pieces of shop equipment.”
First, we need to drill out the holes for the screws that will hold them together. While the two layers of MDF are glued, the countertop and the MDF will only be screwed. The oak countertop, like any natural wood product, will expand and contract with humidity changes. If it were glued to the MDF, the difference in expansion of the two layers would cause the countertop to buckle and curl.

Geometric shapes are made from straight or curved lines such as circles, squares and triangles. Their easy-to-recognize and often symmetrical patterns offer a sense of order, efficiency, strength, formality, but to some may be seen as uninteresting. Squares and rectangles are the predominant geometric shapes seen around us, not only in furniture, but in all areas of life. A circle has no beginning or ending, making it complete and inspiring thoughts of nature, perfection, unity, initiation and inclusion.
As I was handling the 2x4's, during the routing, I realized that I really wouldn't be happy with the look of the bench, if it were made from these unfinished boards. They had stamps, pencil marks, and more importantly, incipient splinters left by the saw, none of which I wanted. And I was remembering what other shop furniture made from unfinished pine had looked like, after a few years in the grime of a shop.
Grouping George Nakashima’s The Soul of a Tree and Jim Krenov’s Worker in Wood with Nick Offerman’s Good Clean Fun might seem sacrilegious, but we like how the trio’s perspectives encompass the diverse spirit of woodworking. The older books combine photos of exceptional work with serious reflections on the nature of craftsmanship. Nick is equally passionate about wood and woodworking, but he’s more willing to admit that he’s enjoying himself–a good example for all of us to follow. 

Thanks Chris! I found this page while looking for a link to your e-mail address. I recently finished your erudite volumes on workbench design, and am about to embark on my own bench inspired by your take on the Holtzapffel design. As my vices and planer arrive, I’ve been agonizing over whether to use SYP or rough maple for the top. I don’t have a big budget, so all-maple is not an option. But after reading your ten tips here, I’ll stop agonizing — all SYP it is! This is, after all, my first of what I hope are at least several handmade benches. Your scholarship and craftsmanship are truly inspiring.
Another aspect that might irk some buyers is the fact that the capacity of this bench is less than great outside of weight. The top’s surface area is a bit on the smaller end, though its length is more in line with larger models. The width though is less than two feet which can limit some projects. Similarly, the vice capacity is the second smallest on our list at 4 ½”, though this too can be modded with optional additions.
