I’m building my second bench. I built the first years ago with wood from old machinery pallets – mostly oak and maple. Mortised the legs into the base, and pegged ’em with 1″ dowels. Of course, the legs warped a bit, but that made everything tighter and stronger. The top is 2″ thick Ash, one board cut in half and joined side to side. Wrapped a maple apron around the top, and I think I screwed the top from underneath to the leg braces. Solid. Over time, built a cabinet under for 3 drawers and a small cabinet door. Works for me.

Stop it. Really. I mean it. Pick a height between your thigh and waist that seems right. You’ll adapt. Don’t worry about your back. You’ll adapt. If you are really uncertain, make it a little taller and then cut down the legs. After a decade or so, your work habits will put a magic number in your head. You’ll have built enough furniture that you will know your number. Until then, pick a number.
The 84-906 fits this bill perfectly as the table offers all of the qualities and features that you would expect but does not truly blow you away with any of them. For instance, this bench is made out of rubberwood. This wood is decent in that it provides the strength you want, but it is also extremely porous and rough-grained. The porous nature would generally make it susceptible to rotting and staining, though the bench has been lacquered. The rough grain will potentially cause tools to dull over time if you do not regularly relacquer it.
I used the factory edge of the half-panel of hardboard as a guide for cutting the ply. I wanted to cut a 5-1/2" strip, and my saw cuts 4-1/2" from the edge of the shoe, so I wanted the edge of the hardboard 10" from the edge of the ply. So I set my combination square to 10", and used it to mechanically set the distance. Hint - if you need two things to be precisely the same length, try to avoid measuring them separately. Use some mechanical mechanism for setting the distance.
Workbenches have flat tops, though sometimes at the rear there is a cavity called a tool well that contains tools and components (and prevents them from falling off). One advantage of having the well set into the top of the bench is that, even with a variety of objects in the well, a large sheet of material can still be laid flat over the entire surface of the bench; the contents of the tool well offer no interference.
I marked the holes by putting a dowel center in the end of a long piece of 1" dowel. Run it through the holes in the base plate, and bang on its end with a mallet. Rotate it a bit and bang it again, and repeat. Odds are the dowel center won't be precisely in the center of the dowel, so you'll be making a small ring of marks. The center of the hole is, of course, the center of that ring.
Remove the jaws and route the edges that you could not route while they were still attached. Then use a roundover bit on all of the corners except the inner edge of the inner jaw of the end vise. Give everything a lite sanding, and apply Danish oil to the inner surfaces of the jaws. (By "inner surfaces", I mean those surfaces that will not be accessible when the vises are assembled - the inner surface of the inner jaw, that bolts to the bench, and the outer surfaces of the outer jaws, that bolt to the vise plates.)
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.
One aspect of the Windsor Design that is hit or miss is the vice. Notice we have to use the singular when describing it because this is the first workbench that we have reviewed which features only one vice. To make matters more frustrating, the vice cannot be repositioned along the bench. That said, the vice does at least have the largest capacity out of any we reviewed. At 7” capacity, the Windsor Design vice can secure any size workpiece you may have.
Ok, I’ve had my morning coffee and now it’s about time to get out to the shop to see what I can do to make that bench a little more pleasing to my eye. I like that Craftsman flair idea. That was my intent at the time I built it, too bad I got lazy and rushed the job. It’s not like I was going to make hundreds of benches for someone else and would never see it again. I should have taken the time to make it the way I wanted it to look. This could keep me entertained for awhile. I see major surgery in the forecast! Gotta plan it all out just right.
The description below is an outline for how the course will proceed.  We intentionally maintain a level of flexibility in our curriculum to adapt and respond to the needs of each group of students depending on aptitude.  Each project has a basic standard of completion as well as design opportunities for elaboration and exploration of more advanced techniques.   Our instructors will guide you through projects as is best suited for your ability level.   
The decision to be made with respect to the end vise is whether the support plate should be mounted to on the inside or on the outside of the stretcher. Mounting the plate on the inside of the stretcher reduces the reach of the vise - it can't open as far, because the support plate is back from the edge by a couple of inches. But mounting the plate on the outside of the stretcher means that we need to add some support structure for the inner jaw of the vise, which the legs would have provided if we'd mounted the plate on the inside.
Students will make two pens at the lathe, one of solid wood and one of your own design built up from several pieces of wood. Since turning pens is a quick process, we will have time to teach you how to choose woods, how to prepare and mount wood on the lathe, and several of the more popular finishes. We will cover safe operation of a lathe, demonstrate how to use common woodworking tools, practice tool sharpening techniques, and discuss options for what kind of lathe you might want in the future, from a small pen lathe to more robust machines that can handle much bigger projects. Bring clothes that can get dirty.
Require the woodworker to be able to read the plans and to transfer images and dimensions from the plan to the lumber. The wood has been planed and all glued panels are completed unless over 14 inches. If panel required is over 14 inches, one glue seam will be required. The woodworker needs to be able to do some cutting, jointing, assembling and finishing. White Kits do not require planing. White Kits supply all of the needed hand-selected dimensioned lumber, but woodworking knowledge and tools will be useful to complete the project successfully.
Our sizing options range from 6′ x 8′ to 13′ x 36′, and even larger depending on your chosen style. We’ll work with you to design a custom solution based on your needs and property, with many door options, window options, trim colors, shelves, siding and roofing choices to choose from. We deliver a large portion of our sheds fully assembled using our lightweight “mule,” but we also provide an on-site build option for those really tough to access sites.
@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.
Synopsis: No room in the garage? Basement not an option? Consider what Ken St. Onge did when he needed shop space: He bought a prefabricated shed and converted it into his full-time woodshop. Because a pre-built shed doesn’t need a cement foundation and is built in a factory, it’s much less expensive than building an addition or stand-alone shop on your property. It can have taller ceilings than a garage and bigger doors than a basement, both big pluses for a woodworker. You can put a shed just about anywhere, too. Here’s a soup to nuts look at Ken’s experience, so you can gauge whether a shop in a shed is right for you.
