That sounds like it ought to be a contradiction in terms, Bryan. Could you elaborate a little, if it wouldn't get too technical? And thank you for an enlightening post. I must say, you have an unusal hobby; I am imagining, when someone asks you what you do for fun, you saying, "Oh, I just go out to the shed and marage some steel". Oh!
Maybe you can tell me (though I wouldn't blame you for refusing, after that little remark!): how is maraging pronounced, please?
