I've been eyeing the Kreg Klamp table for a while, but it's small size (21 3/4 X 33 3/4) relative to it's price ($400) have kept me from pulling the trigger. I've been thinking about making my own, and would appreciate some thoughts from you folks with more experience than myself.

In a nutshell, I'm thinking of stacking two sheets of 5' square 3/4 BB on top of each other. On top of that I would center a 4' square 1/8" thick sheet of iron. In the 6" space surrounding the iron, I'd sink in the same Kreg track they use in their Klamp table (or something similar in function). Trim off the excess BB outside of the track, build a base/legs, purchase Kreg clamps, stops, etc. I was thinking of incorporating the iron because I can get it cheap, and when lightly sanded and waxed, it's super slick and impervious to the glue mess I make every time.

Does this sound like a useful table for Glue-ups, assembly, clamping, cabinet making, etc? Anything else I should consider? Thanks!
