30 $ in fastenal , some scrap and you got yourself self some serious jacks, upgradable to 20 tons plus.. Attached ImagesThermal Arc Fabricator 181IDayton 230/140 stickEvolution 14" dry sawafter  12 years of wood work, realized that the best wood working tool is a welder.
Reply:Excellent idea. But the screw and nut are about 20 times stronger than the cut out square tube. Best way to do that would be to leave the square tube intact and turn the nut on a well greased washer. Ive built a bunch of similar jacks using folded up landing gear legs from semi trailers. 1.5" acme threads... and they're free!
Reply:Im well aware abiut the strength difference, and I actually ordered proper big ol washers! But time/ money was tight. I needed to swap bunch of rusted posts out. The picture is confusing, the id of the tubing is  too big for the nut just to sit on top. The threaded rod is 2" , ideal would be heavy wall 2" pipe with a few washers, and gussets to compensate for the cut out. But ratcheting makes it all so much easier! And crackheads will be less tempted to steal them if left under structure.Thermal Arc Fabricator 181IDayton 230/140 stickEvolution 14" dry sawafter  12 years of wood work, realized that the best wood working tool is a welder.
