Meet the Knock-Down Workbench

Please note that there is an earlier post with more details about construction, which can be found here. Thanks!
It’s finished. Last night I put the final touches on the workbench. After a few coats of finish on the vise it was ready to assemble and put to work. I immediately made some bench dogs. It was a true revelation to have a real vise and a relatively stable surface. It’s not a massive, stationary bench, but it’s so much more than I had. It was made with hand tools, with the exception of the use of a drill for the many, many holes.
Here it is with the vise handle removed and ready to break down. The gray discs on top are what I call “bench slippers.”
They are short bench dogs with nylon furniture glides attached. When the legs are removed, and the surface is flipped over, the slippers are inserted and the bench can be slid around on wood floors without damaging them. More on that later.
My design is literally full of holes. I made a large array of dog holes in the surface. It may seem like overkill, but I expect to use random things like the Veritas “surface vise,” as well as using dogs to box in various rectangles on the surface. With only 1 vice to handle all tasks, flexibility is key.
The vise works quite well. It feels very stable and predictable. My only complaint is that it screeches a bit, even after extensive waxing. Without a drill press, the angles on the screw and the 2 guide rods are not perfect, so there are various slightly opposing forces involved. It works great though, being both smooth and steady. The external garter works like a charm. The sapele face/chop is working great and looks amazing. There are more details on its construction here and here.
If I did not have soft wood floors (bamboo) I would have bought a metal vise and been done with it. Sometimes things work out for the better, because I really like this vise (so far). If you have the means to make the bench but not the vise, buying a metal one is definitely an option. The vise is by far the most complicated part of this project.
Once broken down, which involves removing the two leg assemblies, the main surface sits flat at about 5″ tall. With the 2 leg assemblies, it breaks down to a stack about 8″ high (+ the glides).
In the end, I had purchased about $40 worth of wood for the bench itself ($30 for the poplar top, $10 for the 2x). The vise is scrap, other than the face. If you have scrap around you could use that and make adjustments to the design. I bought knobs and long carriage bolts for temporarily joining the leg assemblies to the top, but don’t think I’ll need them. I used about $4 worth of the huge sapele board that I bought for this and other projects. Add $20 for the hickory dowel and we come in at around $64 for materials.
Here’s a link to a SketchUp file of the final build. There is no joinery in the Sketchup. Dog holes are represented by black cylinders so they can be rearranged. Please keep in mind that I am left-handed. If you are not, you might want to consider the orientation of the vise.
If you build it, please let me know, as I’d love to see it out in the wild. Please note that it does flex in the short direction due to the lack of stretchers there. I may add some supports that can be temporarily bolted in, but I want to use it a bit first. It’s quite solid in the long direction due to the existing stretchers.
Now I can actually build some stuff… Next comes the tool cabinet!

Kenneth, congratulations on a job well done. You’ve passed me by a long shot in the bench construction race. May you get years of use out of your breakdown baby (or, may you get permanent shop space sooner than you could imagine and build you bench’s non-breakdown big brother)!
Thanks Dyami! I’m hoping for real space some day, but might be able to use the vise for a long, long time.
I could just beef this one up some day with permanent legs and more bulk, and use it as a second bench.
How’s your bench coming along? If I were designing something more permanent it would have taken me longer too.
OUTSTANDING!!! CAN’T WAIT TO SEE IT WHEN I VISIT SOON.
That’s a nice looking bench! To be honest, I hadn’t even thought of handedness until you mentioned it, likely because with the photos in this post, I assumed that vise was on the front of the piece!
Thanks Bev!
Thanks Steve. The vise is at the front technically, but it serves a hybrid purpose since there’s no weight allowance for two of them. The long edge on the left is actually a little overhang to allow for the use of small clamps, so the vise has to be aligned to the right. It could be made right-handed just by putting the vise on the opposite short side.
Without the overhang it could have been full width. I originally wanted a twin screw there but didn’t want to push it with even more holes in the 2×4 and more potential alignment issues. I think it was turning 17″ of screw threads in 1 1/4″ hickory that really turned me off.
Wow – a shop smaller than mine! You give me hope… and inspiration. Great bench.
Stop by my (slightly larger) shop when you get a chance, at: http://bowsaw.wordpress.com
Kenneth,
A great small bench (I’m envious as I have a bigger one; but as I’m moving across the country, I need to think small and portable. The one issue I see is side-to-side racking if you use the vice for holding wood for planing. Beyond that, it is a nice small piece. Good ideas for my own eventually.
Thanks Anthony! Best of luck with the move. If I had some space where a bench could live permanently (even a small one) I’d build one that’s much more sturdy, using removable bolts, so I could knock it down just for the move. This guy is more portable because I have to lug it around a lot. Chris Schwarz has a design for a big beefy one.
It does rack a bit from side-to-side. I wanted to focus the strength in the long direction, and am considering adding temp stretchers on that axis. It’s just more stuff to deal with each time it is assembled, so I’m waffling.
Thanks Ross, and welcome!
I’ll check your blog out now and hope to see you there.
Very nice! I have a basement workshop where I just built a full-size Roubo bench (see my blog for the gory details), but I’m talking to the local Parks & Rec dept. about doing an adult ed class on basic hand-tool woodworking. The school doesn’t have any industrial arts facility (oy, how the times have changed!), so I’m considering some kind of portable or at least luggable bench that I can use in their art room or cafeteria. I’ll probably do Roy Underhill’s small Roubo, since the legs are removable via massive sliding dovetails.
Thanks Steve and welcome. Nice blog! I wish I could have made a permanent bench (even a small one) but it’s not in my current reality.
Hi! I’m actually in the process of designing my version of your bench, trying to bootstrap it with the few tools I have at hand (no workmate…). My current plan is to cut most pieces from a beech countertop (and find a nice nordic-sounding name for it when it’s finished
How did you attach the top to its frame? I see no screw holes so I guess it’s glued… Did you account for wood movement or is poplar stable enough?
Hi Damien! Sorry, I missed this comment before.
I didn’t account for movement at all in this thing. It’s very brute-force, and screwed together. There isn’t a lot of humidity variation in my area. If it were intended to be kept in one piece, and be used for many years, it would have been a very different story.
No problem
As you might have seen on lumberjocks, mine will be a little different, bigger and a little more permanent, since I have the room: http://lumberjocks.com/cDlm/blog/series/3915
