I build Norm Abram's rolling torsion box work bench
Everything I thought it would be and more! Lightweight and strong. This is before it was covered in 3/4" MDF (Another bad phone camera picture!)
Should have spent a few bucks on Norm's plans - I made a few errors that cost me another half-sheet of 3/4" Chinese cabinet ply (really crummy plywood for cabinet work, but fine for shop use!)
