fishlessman, Mike, I think I see where I went wrong in assuming 160 rated casters wouldn't cut it so I stand to take my whipping. OTOH so I don't go astray in the future are you then saying if he had 160# casters on all 4 legs they could hold an even weight distribution of 640 pounds? In further looking at the picture plus now knowing he plans to place his table on a paver patio I still would get rid of those small plastic casters as my experience in my workshop is that they don't take much abuse at all.
