I have a two-stall engine house made by Heljan. It has a total of four smoke stack on it, presumably for some wood or coal burning heaters that are against the walls.
I need some of those conical "hats" that cover the tops of the smoke stacks. These "hats" need to be about 7/16ths of an inch in diameter, and maybe about 3/16" tall (dimensions are approximate).
They look like this:
They do not need to be "see thru" like these. I would settle for just a conical piece of plastic or whatever to glue to the top of the open stack.
I have tried cutting circles out of heavy aluminum foil, paper, and coke can aluminum, slitting a radius in it and overlapping the cut radii to create a cone. The aluminum foil is too lightweight, as is paper, and deforms before the cone can be created. Aluminum can material is too heavy to work with.
I would welcome any ideas on how to create these smoke stack covers, or use something that is "outside of the box" that I have not thought of. You know, something from the hardware store, Wal-mart, etc.
