I'm looking for smoke stacks for my Open Hearth mill. They don't have to be finished products - ideas for building them or re-purposing something else are welcome. Here are the requirements:
- Very tall - in excess of 28" (preferably more or extendable to a longer length)
- Metal appearance (not brick) and straight (not tapered)
- Hollow - I will be putting smoke units in these myself.
- Diameter - 4" or less
NOTE: I have already considered (and own) Lionel's 6-14142 Industrial Smokestack. It's smoke output is anemic at best.
If you have any ideas, please post them here.
