Joss has a Copper Chummy tank made exactly the same way as a regular chummy tank, painted you would never know, and no doubt Brass would also work well as Henry says. When I made my tank with soldered seams I used steel sheet and tinned the base using the type of solder paste you would use when tinning a panel for lead loading, I found that it was possible to maintain control of distortion. Henrys suggestion of tin plated stainless steel is interesting, I imagine it would solder well but stainless is harder to work so it might be difficult to double clench the seams.....But then I am just an amateur shed bodger not a professional so I was probably doing it all wrong anyway.
