Have not had chance to locate earlier post on stands and search feature seems frozen at the present time but I strongly recommend looking into the torsion box type of stand . This is tremendously strong and rigid especially if bolted together with 3/8th "or1/2" threaded rod. I have made a bench this way which is almost immovable but could be taken down if required in the future .A frame of 2x4 with a glued and screwed skin of plywoood on both sides creates the ' box'. Stresses are then distributed along the long edge of the plywood instead of just the legs. Using large washers and nuts threaded rods can be tightened with a wrench to great effect.
Just a thought..........................
