To All,
A whitesmith worked in and still does work in tinplated iron or steel.
 Sometimes it also refered to those workers that filed as forged iron 
to a "white" surface. Pi times the (diameter plus or minus the 
thickness of the ring) is for outer or inner dimensions with no 
allowance for a forge weld which is often left to experience.
