If it just needs to be "semi portable", then just build it in two halves, bolted together. You can use bolts, washers and wing nuts to bolt on the legs, and then build "normal" benchwork on type (aka the HCDs). you can diassemble it when necessary, but it will still be built heavy enough to be semi permanent.

That seems to be the consensus by the other members of the forum as well.
