I was basing my comments on your statement, forgive me for not knowing off the top of my head what is in your fishroom. Just for interest sake, what is the single largest tank on one of your home-made stands? 2000kg from a heap of small tanks is a different kettle of fish to >1200kg from a single large tank.
Still, it does not change the fact that Henward, or most people in fact, do not have the access to the right equipmen or the basic knowledge to be confident enough to make their own steel stands. I am by no means afraid of a bit of DIY, I have built many timber stands for large tanks, but wouldn't even entertain the idea of building a steel one given that I have zero knowledge of welding steel, or anything related to it. Good on you for having the ability to do it yourself, but don't expect other people to rush out and try it simply because you wrote a brief step by step account of how you did it yourself.
*edit* and whats with the after every post? Are we supposed to worship you for choosing to bestow a smidgen of your vast knowledge upon us mere mortals?
