I can set a loader bucket on it and weld a new wear edge on without crushing it.
I can set a 500 lb tractor engine on it without worrying about bending it.
I can clamp pieces to it to prevent them from warping when I weld it.
I can tack pieces to the top of it to assist in assembly then cut them off when I get it all welded together.
I can pound on it and flatten stuff.
I can drill and tap holes in the 3/4" top to assist in clamping things down.
I can hook a come a long to one side and straighten things.
I can heat things on it with the rose bud torch without warping the top.
I can clamp parts to it and paint them.
You can see the doors on one side where I store all my cutting and grinding wheels, welding and brazing rods, clamps, jigs, magnetic cutting bars, angle brackets, etc and keep them organized.
