I am just about to purchase some mild steel tube so I can make myself a luggage rack. I've done some searching but can't find a definitive answer...
What is the most appropriate thickness of round tube to use, as in wall thickness and outside diameter? Some posts have suggested 1mm wall thickness and some 2mm? What thickness are manufactured racks usually?
I know it will be a trade off between weight and strength but what's my best bet? I read one post that suggested 1mm wall thickness would get a bit thin on the outside of a curve due to the stretch.
My plan is to use a plumbers spring inside the tube and bend it using oxy acetaline. Will this be ok? I haven't got a pipe bender....
