But before you go out and buy steel for an entire drum kit, wait and see how mine goes as far as working with it. THe steel bends around the shell but takes some force to get the end of it flat. I might need to go to a metal shop and have it rolled.
Thanks for all the info. I'm pleasantly surprised how reasonable the cost is.
Regarding getting it to curve: I wonder if you could make the steel curve using a rolling pin and some gentle pressure. I'm not suggesting wrapping it around the rolling pin, but rather have it act like a rounded "corner" that you could pull the steel around. Gentle angle at first, then increase the angle with each pass until the desired curvature is achieved. Anyway, it's an idea.
Another thought about the seam: Positioning it under a lug will give it extra security.
Edit: I just went to the vendor: a sheet cut into 6 strips is $77. Booyaa!
Thanks again.
