I drilled from the mark. That way I could ensure that the hole was where it was supposed to be, on the side where the position was critical. I have two 3/8" bits -- a brad point bit that came with my doweling set, and a perfectly ordinary 3/8" twist bit. Brad-point bits are far more precise than twist bits -- they're more likely to start where you want them to, and they're more likely to stay straight. My problem is that my brad-point bit wasn't long enough to go through 3-1/2" of wood. So I started each hole with the brad-point bit, then finished it off with the twist bit. I clamped a piece of ply on the back, to reduce tear-out.
There are two books that I would consider highly influential in my personal woodworking path. Darrell Peart’s “Greene & Greene: Design Elements for the Workshop” (Linden) and “Adventures in Wood Finishing” by George Frank (Taunton). Peart’s book kicked off my fascination with all things Greene & Greene. Peart does a fantastic job of covering history as well as practical techniques.
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.
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.
Professional woodworker Jim Tolpin offers solid instruction on the principles of measurement and proportion, walking you through every step of the woodworking process. From design and layout to developing a cutting list, his easy-to-follow style introduces a variety of tools (new and old) used to transfer measurements accurately to the wood. You’ll learn the best cutting techniques, how to prevent mistakes before they happen, and for those unavoidable mistakes, you’ll learn how to fix them so no one will know!
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.
While a strict figure for the bench’s weight capacity is not available, a quick browse through their other stand and bench products shows a general weight capacity well above most other brands. As such, while we cannot say for certain that this bench provides the best weight capacity, it is more than likely that it the capacity is similar to the other products in the catalog.
