Don't worry am doing the specifications for a trangia burner. Darn 4 x 10 aluminum sheets cost $3 a piece! Might perforate the metal with holes to shave some weight if I do the wallet stove in brass thought. The esbit tabs does have a slight smell I do hate the gooey mess it leaves on the cup though. And the trangia design is inverted by the way, aluminum goes over the top and not under as it is more practical. Ron
