Re: Building my first oven!! Help me out.
It's not "square tube", he said he used "metal studs". The metal studs are like thin wall c-channel and available at most building centers. Once the inside or outside is on, it's sturdy but working with it before that is like building a shed out of tissue paper. But, it's cheap as a wall separator/frame. Rather than using angle iron, maybe purlins would be better. But the costs go up.
