Blued anything to be honest, with the introduction of cheap anodised ali' and stainless as the default for polished and decorative finishes- looking for a company to re-blue the cylinder covers on SL Osprey's 1902 Sissons engine proved one of the most difficult parts of the engine restoration.
Thanks for the thoughts on materials. I guess that will push towards my not complaining about the over weight stack just yet. Mind you, with a weight of 9.2kg it puts the centre of gravity of the bare casing and funnel up in the base of the stack about where the funnel stub ends. Cutting the weight to 4.6kg would bring that down to about the level of th top hole for the water gauge 13cm lower!
So I will have to think some more. I would have thought it would be quite strong enough in 0.5mm steel which I imagine even I could bend.
Anybody looking for a nice funnel, new unused and just a little heavy...
Otter's stack is a piece of 7" surplus titanium aircraft APU exhaust tubing, single wall perhaps .020 thick. It's blued in one spot due to a stack fire with a vaporizing burner.
