I've been trying to get a leg up on my Roubo bench project. The workbench I have been making do with is a Sears version of a Workmate, which does fine as a clamping device, but it moves all over the place when I'm trying to plane something. I was really beginning to appreciate a saying I heard once about how "you need a workbench to build a workbench."
But then I had an "Aha!" moment. Recently I came into possession of a board of poplar 3 1/4" thick, 8 3/4" wide, and 6 1/2 feet long. It was rough cut, with a lot of dirt and bird poop on it. I also had been reading Scott Landis' workbench book, and in the chapter on Japanese woodworking workshops, there is some discussion on trestle beam workbenches.
I planed the beam down so that the surface was level. Then I put it on some sawhorses, and put a board of 3/4" pine on the back side of it to serve as a place to hold tools.
Here's what it looks like:

So how can this set up be at all stable? Here's where the 1x4 comes in. I nailed the 1x4 scrap to one of the sawhorses, and set it up so that it butts up against the wall of my workshop. On the underside of the poplar beam I installed two screws so that the heads protruded above the surface by a little bit, and arranged the beam so that the screws rested against the cross beam of the sawhorse.

I installed another two screws so that the heads were above the top surface of the beam, and placed a thin scrap of cherry across them to make a planing stop.

With Japanese planes, which work on the pull stroke, everything locks into place under planing pressure. The plane pulls on the workpiece, which butts into the cherry planing stop, which butts up against the screws. The beam butts up against the sawhorse with the two screws on the underside, and the sawhorse runs into the wall thanks to the 1x4 scrap. Nothing, and I mean NOTHING moves.

A similar setup could be done for western planes, if you made a mirror image of this setup. If you're a lefty, you could use this setup as is. I've tried a variety of Stanley bench planes on this setup, although I was planing left handed, but again this setup is rock solid.
Sawing can be done with Japanese saws, which cut on the pull stroke, because the pull stroke clamps the workpiece to the bench top, again locking everything in place.

By the way, if you ever wanted a good demonstration of the kind of surface that a Japanese plane can leave on wood, check out the light round thing on the side of the beam. That's the reflection of my saw where the handle meets the blade. There's no finish and no sanding here. I just planed down the roughness on the side of the beam with my Japanese plane, which isn't anything special. I bought it used on eBay.
Chiseling tasks work just fine. I generally try to direct chisel cuts so that I am pushing or chopping down into the bench anyway, and I can use the planing stop to brace the workpiece against. I can always resort to clamping the workpiece to the poplar beam if I have to.
I'm still going to make the Roubo, since I actually do use western planes from time to time, I can't see functioning without a vise, and I don't think that this setup is going to hold a face vise very easily. The ability to use holdfasts would also be nice, although I think I could drill some holdfast holes into the beam. The other workbench task that seems problematic with this setup is doing rough planing across the face of the board or on a diagonal for initial leveling with a jack plane or jointer plane, but at least I have my workbench to make a workbench now.
