im building a welding table and i was gona go with 3x3 .120 square for the vertical legs. but a guy has some 3x3 .250 angle for sale for a little cheaper then what it would go for new. so im considering it for the vertical legs. the legs are gona have horizontal supports on top and down low too. what do you guys think? .120 square or .250 angle? ill only save about 20 bucks if i go angle but its heavyer.
