I am thinking about building two identical benchs pictured below.
2'x6'
3" overhang on front and side
0" overhang on the back
high enough to line up with the table saw top (out-feed table)
3" casters with locking action on rotation and axis
Here are some thoughts
Normal location will be end to end against the back wall of the garage. When needed for an out feed table just roll it in place. For assembly table place both benches back to back and clamp together (4'x6' table).
The front bracing is left off to facilitate storage of other roll around cabinets. I am concerned that leaving this brace off will allow the bench to rack side to side. If you think so I might put it in place and fill in the area with drawers and do away with the roll around tool box.
