I like to make my work benches out of used doors I have found that you can usually get really good used doors ( I like Solid Core ) from Used building supply places..They can even be slightly damaged as long as they are flat.The damaged doors are usually quite cheap..Go for the widest possible..Then on top of the door I put a layre of 1/2" donnaconna..Its like ceiling tile that comes in a 4ft by 8ft sht...I set mine up on top of saw horses and that way you can put a shelf part way up for storage...
