I’ve been interested in the idea of a so-called “Moxon” vise or bench-on-bench setup for a while, but there have been many other projects that have taken precedence. The idea of a higher sawing position for smaller cuts just seems like a good idea. Over the summer, I asked a group of woodworking pals what they thought of it, and I got some feedback including “just do it, you won’t be sorry.” Also included was a bookbinder’s finishing press treatise/rant from our friendly neighborhood bookbinder who stated that (among other things) if I really wanted to make something specialized for woodworking, I should go for bench-on-bench. Since there’s a near-zero chance of me wanting to get into bookbinding (sorry, Tom), I decided to go for bench-on-bench.
Unlike Joe’s elegantly-finished vise, I decided to go with the ever-sturdy southern yellow pine for most of the construction, and ordered the Benchcrafted hardware. As usual, the hardware sat for several months while I dealt with other projects.
There doesn’t seem to be much consensus on the construction of bench-on-bench, so I decided that I would stick to the “every one of these is different” rule and make a solid inverted “U” shape for the top and front/back, with some stretchers along the bottom. The stretchers are not for support, but to provide a way to clamp it down. Here are the parts ready for final glue-up:
This is, of course, upside-down. I waited to glue on the rear because I felt the need to do that along with the stretchers. In addition, I used a loose tongue there (with the appropriate diagonal-grain configuration) not for strength, but to keep the top aligned with the rear during glue-up. This might be the first time that I’ve used this kind of joint.
There wasn’t too much to do after that. The next step was fitting the chop:
The chop is a 4/4 piece of soft maple. The Benchcrafted instructions suggest a configuration with the vise nuts for the fixed chop recessed inside, so for no good reason (other than stupidly not doing it the quicker way on the drill press before gluing the front on), I traced the nuts on, and chopped out the waste:
Then, I chamfered the top of the front chop, added the “crubber” (the cork/rubber gasket material that BC includes with the hardware), and did a quick rubdown with some tung oil:
You can see that this is currently clamped to the bench with C-clamps on the stretchers. I suppose that I could add dog holes in the bench and use a threaded rod or something. but this seems OK for now.
I added one more component: a slide-up stop at the rear. Here’s how that looks in the “partway up” position:
It can extend higher, and is held in place with a couple of threaded levers. I’m not sure if adding this was a good idea or not, but the main reason I put it there was to try to get some bench hook functionality. For example, when doing the crosscuts to remove the waste from tenons, I thought it might be handy to take the work out of the vise and lay it along the back. Ditto for using it to stop a piece when cutting a small groove leading to a knife line with a chisel.
At worst, if the stop doesn’t prove to be useful, I can just stow or remove it.
Here’s one final view, with the vise holding a board in “dovetailing” configuration:
This seems to hold securely. I did several test cuts and nothing appeared out of the ordinary. It does seem much more comfortable than stooping down to my (low) main bench to cut stuff. The auxiliary bench that I’m using here might be a little on the top-heavy side now; I do want to add more weight to the bottom. Happily, this should be soon, with one upcoming project that will use this new tool.
