Where do I buy 4″ diameter copper the for locomotive boiler making?

[Simon Robinson 4Participant @simonrobinson4]

Hi

I've worked out that I need 2mm thick copper tube of 4" diameter to make a steam locomotive boiler of 9" in length, for 60psi

How much can I expect to pay for such tube?

Have you any links to places that sell such copper tube?

thanks

Most model engineering suppliers are probably going to list by gauge number so 13 gauge which is 2.5mm and 4 inch diameter is listed by for instance macc models at £3.25 per inch.
