..i machined the lifter from 1" square coldroll steel..took about 3 hours in all...
...that's a block of brass under my stand, and that pic was taken before i made them..
..my extensions are just one inch long pieces of 1" square thinwall (1/8"), cold-roll steel tubing, that i welded to each of the stand's feet...
..welded them with the open ends up and down when the stand is in the retracted position..so any dirt will tend to just fall out..
..haven't had time to paint them yet, or i'd take a pic....lol..
