Finally got a stand made up for my Post Vise. Had to get some plate, pipe and a welder to put it together. The base is 24" diameter, I would go bigger next time. 3" Schedule 40 pipe, 1/2" inch top and bottom plate. The post the vise is sitting on is crooked, I wanted the vise to be straight. Hindsight I probably could have straightened the mount first... It's fairly stable as is, and when needed I can stand on the plate to add weight. I wanted it round to be able to move around in my small garage shop.
