Extruded aluminum is usually very strong. Bishop WiseCarver Inc. sells it for making industrial/cnc type equipment. They are the guys that make the bearings for the shopbot. I suspect that it would be expensive to build a 6'x10' table for the shopbot. I would love to replace/beef-up my y carriage with the stuff. I'd like to find out how much it would cost to build a table if you ever check prices on it.
