ok so update is.... the types of casters they use for the dollys are about 50-70 depending on what wheel material you want to use, based on what surface youll be rolling it on and how often youll be moving it around (smooth warehouse pavement, rough road pavement, etc) and as far as the steel involved mild steel 2x2x1/8 box tubing should be sufficient to hold the eight thats about $75 a stick of 24 ft which should be enough to make 2, we could bump it up to 1/4 and make them double the weight but way stronger, although it might be overkill..
Sooo let me know if your interested those ones from yardarm cost like what? 700-800 each?
