Seriously? Do keep us posted... far as I know, it's not something that 
anyone's ever tried before - it'd be interesting to know how you get on. I'm 
not even sure how you could coat a drum in glue / oxide and get it of uniform 
thickness without specialist tooling.

I've heard of low-speed, low-capacity homebrew drums before, but it sounds 
like you're hoping to rebuild a commercial one...
