I'd be interested in getting my chain re-galvanised. Also my Delta, but I have heard it said that the tip is lead filled, making re-galvanising impossible. Anybody know whether this is true?
I suspect its true that it has a lead filled tip.
Most galvanizing contains a little bit of lead, which melts at a lower temp than zinc. Zinc for galvanizing is typically 0.5 - 1.0% lead.
How did they galvanize it in the first place? Or did they add the lead afterward?
Lead is much heavier than zinc, or steel (densities from memory about ... steel: 7.2, solid zinc: 6.9, Lead: 15.)
Does the tip have a small hole for adding the lead?
Just looked up the original Delta Patent. It seems to imply a cast steel tip, not a lead filled tip...
