So in a nutshell:
As I said the "customer is always right" (we believe in that).
Right now I'm updating the original first post and switching the material to stainless steel.
Let's see what we can do with it.
Forget about the original copper idea.
Stainless steel is the actualy project from this moment.
If we'll be able to do it and work with it, then everybody gonna be happy.
If we fail... then I'll close this thread to not waste your time with a "dead-end" idea.
So I'll keep you all updated.
Subsribe to this thread and come back for the news if you want.
Thanks to everybody for the kind posts and and I'm updating this thread with new infos of the progress ASAP.
