Here's a bit of food for thought for ya.!!! . . . . Why not build 2 small concrete block walls with a plate securely bolted down onto it. Then with adjustment jack nut n bolts thru both to level the RSJ's. Then you could just push a strong bench under neath fasten down then surface it flat and away you go with virtually no material height restriction.
Obviosly you will have Z axis travel restriction but not material height.!!. . . The machine use's and flexibilty regards material sizing become far greater.!!. . . . Imagine some one wanting an old table surfacing or V carving. . . . how easy does that become.? . Ye I know not probable but you get the idea.
The same plate/jack system would work good on a bench thou.

Some time towards the end of the year I'll be building just such a machine that use's R&P and will be used for cutting granite slabs 3x2mtr into work surfaces. This will use the same principle but have a free standing concrete table with a hydrolic tilting frame for loading slabs from near vertical to horizontal.
