I might add, when welding MS, unlike CM, leave a 1/16 gap between the pieces. The wire will penetrate and not ‘bubble gum’ up on the joint. Next time you’re at the races look at each cars ‘welds’ then ask yourself would you feel safe in there?
I would only use .125 DOM tube also, doesn’t have to be .134 because it’s uniform. Just a hoop 1.3/4, cage can be 1.625
