Looking to see if anyone has tried to twist 2" thinwall square tubing.
I have a project where I need to put a twist into about a three foot
lengths of 2" square tube.
I'm thinking that if I insert a loose fitting round pipe inside the
square tube and would then pack the tube with sand and weld caps on
each end that this would stop the tubing from buckling. I have a large
old pipe threader which I'm going to try and do this cold also since it
is rather large of an area to try and heat up uniformly at once.
Any thoughts or other ideas and practical experience would be
