I am building an upright bell for my Conn 20J.  Would like references to books/articles on brass instrument materials and construction, especially info about molds, forms, and bell-spinning.  Links to pertinent websites also appreciated.  The work will be performed in my company machine shop.  Thanks in advance.  Paul.  pro(AT)goes.com
