Mine was made with 2"x2"x1/4" tube and the slip tubes were 1 1/2"x1 1/2"x1/4". Cost about $250.00 back in the 90's . Downloaded plans from internet for $12.00 . Payed to have it cut and TIG welded , casters about $90.00 . About $500.00 invested . sold it 10 yeRS later for $500.00 . Can't do much better than that .
