Mike, I don't think you ever stop learning.  Just a few weeks ago, a member posted a piece of iron no one had ever seen, or knew that it existed.  Joe Doucet posted a Martin #13 camp oven.  It's not in the books, but he sure has it.  Just one more reason to join up and see the whole site.  BTW I love all the questions because other people think to ask things I haven't thought of.   Welcome and glad to have you here.
