I have a 6-pound soft lead billet that I want to blend with linotype to end up with a hardness of about 10-12. What weight of lino should I add?
I don't know the hardness of the lino, but it is 60 years old, for what that might be worth.
This is not a scientific operation whereby a rocketship will fail to land on the Moon if I don't have an answer good to the fifth decimal place.
Just need an approximation.
Thanks. PBSmith
