I'm planning on welding several benches and carts for my shop and was wondering when to use square tube vs. angle iron.
When I made my welding bench last year, I used 1/4" X 1.5" x 1.5" angle iron that I scrounged via dumpster diving.
However, I'm making a new bench for my benchtop drill press and small lathe and was considering using square tube (3/4" x 1/8"). The dimensions of the bench will be 5' long x 30" high x 24" deep.
Any reason why most of the projects I see in books and online use angle iron over tube? Is it just because angle is less expensive? Easier to work with? I would think that one would be able to use smaller tube as it would be stiffer than angle for a given size.
A local rental center carries a 135A Lincoln mig welder which I was planning on using that to weld these projects. I was thinking that the 135A welder (using flux core) would do a better job on
1/8" material than 1/4".Thanks for your thoughts, Aaron
