[SEL] Sticking lead to cast iron

[Ed stoller]

Rick,

Why don't you try to take a little acid and dissolve some copper wire in it, 
then apply to the cast iron to see if the copper will transfer to the iron. 
Maybe John Culp could help us here. In talking to my wife ( of 11 months 
now), her father would dissolve zinc shavings in acid and then use that 
solution to tin sheet metal. You may just have some old pot metal laying 
around for the zinc.
