I understand the silver plating process quite well. Acid is not used. The instruments are degreased in a number of processes and the then goes through an alkalitic bath, then rinsed in distilled water. Then it is copper ''struck'' in copper-cyanide and silver-stuck in a low yield silver-cyanide bath. It is then plated in a full-strength silver cyanide bath. After it is plated the instrument is rinsed, dried and then brightly polished and cleaned again. Thanks for your interest.

Nice video series! Kind of anti-climactic though. I was hoping for a final overview and before and after...

[DCOberloh]

@16mmDJ Sorry, the completed instrument can be viewed on my company web site in the gallery. Thanks for checking out what I had to offer.

I can only imagine how much "fun" that Martin tuba was to work with.

[DCOberloh]

@TheHatTuba Oh yeah. That was a much bigger project then this one. I have a JW York 6/4 project that is similar to that one in the works presently. I hope to complete it this summer. It should be a real beauty when the plating is completed.

@DCOberloh I think I met itsabundy in a tavern in South Seattle. He was leaning in a corner, ciggie in the side of his mouth and drool dripping off his chin..

that was the best 70+ minutes I have spent in a long time!! Other than practicing, of course!
