Built 2 Wing Jack Stands, using Harbor Freight 3 Ton Rams (about $45 each on sale), 1/2" conduit, SS hose clamps ( 2 for backup) and 2 ft x 2 ft plywood (from shipping crates). Referenced examples from other builders on VAF. Biggest job was flattening the conduit in vise on each end. Ground couple SS 3/8-16 carriage bolts into spherical heads. Drilled ends of Ram with 1/2" drill to match. Using 1" to 1/2" reducers (piping at Menards, etc) as safeties to insure bolt head stays on top of ram ! Very solid, not too heavy to move around.
