Hi Colin
As I understand decorative chrome is incredibly thin. (Where it peels it is the nickel undercoat)
Applied even .001 thick becomes hard chrome, although hardness depends on current etc. But in most applications much thicker is applied and hence needs grinding to correct dimensions. The kingpins were plated very thin.
A long story but eons ago I had Seven flywheel splines built up just to enough to fit by chroming. Also misguidely had softened Javelin gearbox thrust washers plated with no machining. De Havilland did in Wgtn and Colonial Ammuniton in Auck.
