My advice? Don't do this. If you have jointer and a planer, use them. If you don't, seriously consider using dimensional lumber that has already been planed and sanded. If you are going to try to clean up construction lumber by hand, using a hand plane is a lot faster and more pleasant than using a belt sander. Except, of course, that to do a good job of planing a board you need a solid bench to hold the board, and you don't have a bench, yet.
When you have the other leg seated, the threaded rods will extend father than you want them to. You'll want to mark them so they can be cut to length. Place a washer and a nut on each threaded rod, and then tighten down the nut to pull everything tight. Depending upon the wrench you are using, and how much longer the rod is than it needs to be, you may find it necessary to stack up a number of washers, so that the nut is positioned where the wrench can operate on it.
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.
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.
With the inner jaw fastened to the bench, I used the router to flush-trim the jaw to the benchtop, across the top and down the sides adjacent to the top (stopping short of the discontinuity between the top and the legs). I'd thought this would be the best way to match up the jaw against the top, but I'd not do it this way again. It was very difficult to hold the router tight against the face of the jaw, and the result was a surface that wasn't as even as I had hoped.
I’ve seen antique cabinetmakers’ benches that are sixteen and seventeen feet long, more than three feet wide, and supported by a dozen drawers and doors—and that weigh as much as a felled oak tree. In contrast, jewelers’ cabinets seem to be on a dollhouse scale, with tiny tools to match. For most of us, however, space limitations preclude the biggest, and the smallest are just not big enough.
The tutorial that I am sharing here was written by someone who built this pallet art just to improve the value of a property they wanted to sell fast and they succeed in it. So you can imagine how wonderful this item must look like. I am assuming you do not just want to make this beautiful pallet art so that you can also sell your property easily. Well, whatever your reasons are, this beauty is able to attract anyone who visits your house.
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?)
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.
I wanted the left edge of the jaw of the front vise to be flush with the left edge of the top, the right edge with the left edge of the left front leg. So the amount of overhang on the left depends upon the width of the front vise jaw. The width of the jaw is, at a minimum, the width of the plate that supports it, but it's normal to make the jaw extend a bit beyond the plate. How far? The more it extends, the deeper a bite you can take with the edge of the vise, when, for example, you are clamping the side of a board being held vertically. But the more it extends, the less support it has. I decided to extend by 1-12", which gives me a 2-1/2" bite, and which should still provide solid support, given that the jaw is 1-1/2" thick. This means the top needs a left overhang of 12-1/4".

Permanent or Portable? This is a distinction that decides much about your bench choice: Is it to remain stationary or must it fold, roll, or otherwise make itself scarce between jobs? Large, heavy benches are more stable and, in general, more adaptable to different jobs (sometimes several at once). But the bigger the bench, the more hassle involved with stowing it.
