Been lurking on forum, this might be my first post.
Comeback player after realizing my miserable range just a mouthpiece problem from grade 5 to Freshman at Illinois State Univ.
I suspect I'm becoming a small bore trumpet junkie.
I have a lot ( a LOT) of old cornets/trumpets with worn vavles. Most not tremondously collectable / valuable.
Anybody done home-based copper valve plating. Honing? Casing burnishing? I suspect nickel plating at home is a bridge too far, but I'm considering copper plating at home.
I own a couple of soutbend 9" machine lathes that might be used for honing.
Am willing to do some homework and report back, but would appreciate a nudge in the right direction to get started.
