You know from the replies I got on another board, I think I was confusing people when I said piping, since that probably indicates the edging around the metal plates or something along those lines. What I meant were the hoses that look like connectors, or the steam pipes. I think the Lego hoses might actually work.
Did you mean the tubes like in this schematic? The ones that look like a bunch of single hole round pieces stacked on top of one another? That's what I thought you were talking about.
