You have never climbed inside a tubular steel headstock
Richard so how can you guarantee that every bit of surface
inside the stock has been galvanised.  In any event
moisture condensing on the surface of the bell when
humidity is high will then run off onto and through the
tubular steel stock.  This water will contain copper in
solution from the bell and this solution will strip the
galvanising off the stock.
