Anyone have an idea the difference of expansion rates of Steel and Brass.
I'm into a Chickering Grand and am planning on trying to anneal them
puppies. Reason for asking is wether to remove the screws and drop screws
or leave them in during the annealing process. Any one have some thoughts?
Regards,
Joe
