The copper "dip" was part of the hardening process,...

T'aint electroplate copper, Chris!Originally posted by Chris Haynes View Post
That risks hydrogen embrittlement.
Certainly you have seen crankpins with the copper, as well as pushrod adjustors, Pan rockerarms, and the like.
I was told the parts were literally submerged in molten copper during the heat-treat, and then machined afterward.
Certainly not a cheap process!
Ulf needs the nickel that nobody wants to produce correctly, even the platers with antique motorcycles themselves.
