efficient shop/garage help

[Canucklehead]

When i was building my garage a local shopping mall was being renovated and a buddy of mine was doing the steel work. He phoned me up and asked to bring my trailer down there and he will show me why when i get there. Well i got there and he had scored to wooden support beams the were 22"X10"X22'. Perfect bench tops for our garages. I built some 4x4 supports for them, left room for a 2x4 shelf underneath, covered half the top in sheetmetal and walla!, perefect bench for anything i could throw at it.
