As I am building out a plant with a pm research horizontal boiler, I am looking for options regarding chuff Pots and water tanks. Would like them to match the general look of the boiler, so probably black and riveted. There doesn't seem to be much offering for these components so I am considering soldering and riveting my own. I tend to think myself pretty handy when machining, but for the tank end caps I would like to have spun or pressed to give it a nice rounded appearance to that of DemonOZ's excellent work. I feel fairly confident I can print or machine dies from alum. To press/hammer/spin these end caps, but would prefer to buy something off the shelf haha! Also with how expensive large diameter copper/brass pipe can be, wondering if anyone knows a good place to find a chunk without buying a 10' tube! Looking for at least 2.5" diameter for the chuff tank and probably at least 3" for the water tank, but will probably end up making both from the same. Would love to see any examples that people particularly like or have made themselves. Trying to get inspired a bit more!!
