Re: Core Boxes: Why were they usually made before the pattern?

Cover core patterns were the most common type that you would build the core box around the pattern and then add the metal thickness to all surfaces in the box. This assured a perfect uniform metal thickness. At this point either the pattern or the core box could be worked to completion. Type of patt...

Re: Bagley burner install

Re: Bagley burner install
