I wonder exactly the same thing. The work bench I built used doubled
up two by fours for strength but I used diagonal bracing on three
sides for rigidity. See http://tinyurl.com/bqd4k
This bench doesn't move when it's not lifted on its casters.

The short answer is that the lever in the front of the workbench
twists an angle iron under the bench, which, in turn, pushes up on 4
2x4s that act as lever arms to press the casters to the floor. When
retracted the casters fully retract so the bench is sitting on solid
wood feet. When lifted up the feet are raised a little over 1/4 inch
and the bench is moveable. If you want the gory details, email me and
I'll send you a more detailed description. You can find my email
address on my website.
I think I understand your explanation. I will definitely have some sort of
retractable wheel mechanism on my next bench, and your way gives me one more
One thing I also want to add is an easy (really easy) way of levelling the
table. No floor I've ever encountered is completely flat, so if you move
your bench (and if it's got wheels, you will), you have to level it again.
I haven't thought about it much, but I worry that anything like extensible
feet would just ruin the structural integrity gained by all those triangles.

I wanted the bench top to be flat but I see no reason why it needs to
be absolutely level. If it were used to align with another piece of
equipment or table then I could understand why that might be useful
but, to me, the value of having a rock solid feel is significantly
higher than having the table level. As you point out, it will be very
difficult to make levelers that will be as solid as the base with the
diagonal bars. While it is possible I don't see that it is worth the
Don't let the semantics distract you. It's flatness that I'm really
interested in. If the table support frame is absolutely rigid, unless it
only has three legs it's going to rock until the fourth leg's length is
adjusted to meet the floor. It's an overconstrained system. If the frame
isn't absolutely rigid, it's going to change its shape to match the floor,
which is also bad.
I already experience this with my new router table. I'm always moving it
around, and it's very rigid over its four legs. When I need to lower it
from its wheels I just shim one of the legs (or keep moving it until I find
a better spot, which is a pain). But a router table is a lot lighter and
takes less abuse than a workbench so it's not a huge problem. I expect I'll
get away with an extensible foot if I ever get around to adding one.

Ok, I understand. You're right, if the floor is not only tilted but
also not planar then you have lost the advantage of the rigid base -
the rigidity actually works against you. In my case the garage floor
is reasonably planar so I can always find four points of contact by
jockeying it around.
Let me know when you've finished your bench and what you come up with.
