A thick and large pressure tank ...

[Sumpter250]

there were never a "pressure" while I built this tank. On the contrary, I was very happy with every progress because I have entered a new territory with every step which never I have done before.

Bernhard, See ? The greatest place to live life really is, the sharp leading edge, of a learning curve.

Sufficient......as in, looks like the right number of rivets for that tank, and its purpose.

All the wood shingles on my buildings, are individually hand cut,hand applied. Yes, I know the effort you put into that model, and because I know I praise.
