I am in the process of designing a miter bench for a new shop (typical – saw and tables on top, storage underneath) and need some advice regarding the construction of the top. I haven’t done much cabinetry, and was considering building a torsion box top (as two of the spans are fairly long (around 38″). I have also seen a design that built a frame from 2×4’s on the flat (may have been a Norm design). Another alternative was just to glue 2 sheets of 3/4″ MDF with a hardboard top, but haven’t I don’t know whether I would have a problem with sagging over time with MDF as I haven’t used it for construction projects before.
Any suggestions are appreciated. If the torsion box top is the best way to go, is there any benefit or detriment to using MDF rather than plywood for the skins?
Thanks,
Bruce

Are you talking a bench for a power miter saw? I think a torsion box top is way overkill for that. It doesn't need to be all that flat.
Just use legs every three or four feet. Since the bench doesn't move you can just shim under the legs to get the top flat.
I used 3/4" CDX plywood for the top. It needed a little sanding, but it's perfectly fine for a saw bench.
I made a 6 foot bench from 3 layers of MDF, oiled and varnished the top, edged with 6/4 oak 1 1/2 year ago (no replaceable top) and it has been great so far. I don't used it extremely heavily but I use it a lot and has held up fine, still perfectly flat.

Mine is just a series of plywood cabinets, with a MDF top with a laminate topping. I have screwed a piece of angle aluminum to the top to act as a fence. There is a piece of wood and a tape measure on top to measure cuts. I use a sliding stop to make accurate and repeatable cuts.
The base for the saw is just a lowered shelf, about 8"" or so below the table surface, and a miter saw sits in that space. Shims and blocks elevate the miter saw to the correct height, and line up the saw with the fence. The fence has elongated holes in it to make it slightly adjustable too. I suppose you could elevate the fence, too, but I preferred the clean look of a top which nothing to interfere with the surface.
