Re: [TCML] keeping primary copper tubing nice and shiny
Hi Frank and all,
I'd be interested in getting the nickel plating recipe, I used to
be really into that stuff and made my own recipes for various metals
(some better quality than others obviously.) In case anybody is
interested I did have some luck with silver plating, and my recipe
contains no cyanide, It is mostly potassium iodide which I believe is
not a controlled substance and should be easily available from
chemical supply places. The primary cost will be a silver anode,
sterling seems to work well enough. It plates pretty well and
polishes good but under heavy handling will not hold up (the repairs
to my trumpet have pretty much worn through again 2 years later.)
Than again I never bothered to clean my surfaces well so perhaps it
will work well enough for coil duty.

The web-page needs updating, some of the ingredients are not really
necessary or incorrect altogether (NaCO3, not NaHCO3.) Feel free to
experiment, some say calcium ions help to make the surface more
durable at the cost of luster, never tried it myself so I cannot say.
Scott Bogard.
