I just started MIG welding recently and have come up to a problem.... I ran out of steel tubing to weld, I bought some at the local salvage yard but they don't have anymore 1" 16Ga tubing. Anyone know of a good and relitivly cheap place around Chicago or online to buy steel tubing? I hate to have to pay $23.00 for each 6' piece of 16Ga mild steel at Menards; especially since I bought the last batch for $1.50 a foot. I need about 18' more to finish building the wrap around supports for my benchtop in the garage.

Thank you for your time,
Dan Baleckaitis
