I have a few larger projects coming up this spring (bunk beds- Table for 10) as well as a few big ones to finish (16ft skiff, 20ft mini trawler) so I figure it is time to build my workbench! so while walking the hardwood dealer last trip in town i found this!

11ft 3-1/2” x8” Ash
I had it cut to 7ft and 4 ft… took to the local HS to have planed and am now considering what to make…
I like mike dunbar’s bench that uses a wide piece of hardwood for the front and plywood for the rest… seems easy to build and will stay flat….
md bench

But I do not like that the only support for he 3/4 ply is on the sides and the legs mortise through the ply in the back.. seems like it would be weak… I am thinking a torsion box under the ply section…
I am also not big on the wood screws because of the price… not sure what kind of vise I would want… any Ideas or suggestions?

Well, just based on the picture, I’d agree about the support for 3/4 plywood. The first thing that occurs to me is to laminate two sheets of plywood, making sure that it is REALLY precisely held when you glue it.

Another way is to buy a sheet of the 1 1/4” T&G plywood used for flooring, instead of the 3/4 stuff. It’s pretty darned stiff.

As for the wood screws, I can’t tell from the picture – too small, but on many projects, I’ve managed to find a way to use T-Nuts instead, although in some cases, you have to split the lumber lengthwise and embed them in, then re-glue it, but they hold up MUCH better.

A torsion box is a hell of a lot of work… I think Bob has the right idea, laminating two thicknesses of plywood together for weight and stiffness.

I have been studying workbenches for a couple years. I have not yet decided which design is right for my needs. I recommend vertical stretchers between the legs, maybe even one run down the center. With these stretchers tying the legs together properly and attached securely to the top you get a half I beam effect. I believe this would give much more support. The idea of a torsion box is good but most the ones I have seen used have cabinets built under them supporting them in the center. Let us know in a future post what you decide. I am going to study that bench myself. It looks like a nice design.
