As I am getting closer to attempting my first frame I've got a question regarding tubing suppliers. Ideally I'd like to buy some steel tubing locally to practice mitreing and tig welding the joints.

My first few tubesets will probably be the cheap nova cycles tubing, just so I can get a feel for how everything is. Is there a stock steel tubing size that suppliers carry that I could buy in 10 foot lengths to practice with? Is 4130 going to get me close in terms of welding for practice?

Thanks for any input
