Hi everyone, I am planning on building a dual tank stand that will have 2 x 3ft tanks on it - one above the other. I would like to build the length 1.2 m but want a brace in the middle. Q1: I am planning on using 38 mm mild steel square tubing. Is this overkill and could I get away with 25 mm mild steel square tubing? Question is am I prepared to risk 2 x 3 ft tanks on saving R500 on the build. The stand is going to take about 200 -300 kg. Q2: I have never learnt how to weld so I want to use connect-it blocks and pop rivets. Opinions please? Thanks for any and all feedback.
