I am sure a layer of copper is needed before chrome is applied anyway... am I right?
Correct. Chrome doesn't bond to steel very well unless it is very think (thousanths of an inch), and naturally, nickel, which bonds to steel and chrome isn't very self leveling. Thus, steel is copper plated, buffed smooth, then nickel plated, and buffed again to achieve a flat surface. Chrome is then electroplated on, and buffed. The other two metals give a flatter, deeper finish. The triple plate coatings tend to only be millionths of an inch thick, whilst being deeper, smoother and more hard wearing than industrial (hard) plating.
Who is the moderator for the Birmingham section?
Just like the rest of the forum, AFAIK, just Hippy and VB. Why?
