When I was doing my workshop, I had a bunch of wall cabinets given to me, along with a large base cabinet about 6 feet long and 32" wide. I hung up the wall cabinets and was about to throw away the big base cabinet when I had a brainstorm. I had 4 3 wheeled casters which I mounted on the bottom of the base cabinet so I could roll it around. I then put a plywood top on it with a pine 1 1/2" board laid flat around the perimeter on two short sides and the long front side. Then I hinged a 30" piece of plywood on the back side of the cabinet. This also has a 1 1/2" pine board attached flat on 3 sides. When I swing up the piece that is hinged, it makes a flat worktop 62" wide and 72" long. When I'm not using it, it is folded down and I roll it over next to the wall out of the way. It only sticks out about 34".
No one lives forever, the trick is creating something that will.
