A couple of tidbits that I just came across… kinda makes me giddy since it may simplify the construction of this drum extensively!
THERMAL CONDUCTIVITY
Porcelain enamel is not a thermal insulator, but it is a relatively good heat conductor when applied in thin coats. Its emissivity characteristics are particularly good. Normally, porcelain enamels are applied so thin there is only a very small temperature gradient through them.

Enamel is a relatively good heat conductor when applied in thin coats, however it is not a thermal insulator or diffuser.
Not too worried that doesn’t diffuse heat, that is what the aluminum will be for…
oh, and it’s recyclable (not that ss/aluminum wasn’t, but good to know this is too.)
