Hey guys,
Been lurking for a while as I've been focused on other things. But I came across something I'm perplexed by.
An instrument, much like a steel drum in spirit. (So, sheet steel banged into a dome, then notes hammered flat into it.)
In the discussion about making the things they're very "hand wavey" about the steel they "came up with" with the help of some German manufacturer.
Most notably they describe 'nitride hardening' the steel once in form in a 600 degree C chamber with an ammonia atmosphere for "a number of hours."
Now, as I've decided I want to make one of these things I've got to ask.
Does that make ANY sense?
Or are they just heat treating/hardening the thing since it's 0.032" thick?
I'll try to find the original reference for the insomniacs among us.
