I found this great series of videos on Youtube. The first time I saw this video was at my very first blacksmithing class with David Norrie a couple of years ago. This video shows David and several other talented blacksmiths making a reproduction of a beautiful iron gate designed by the great Samuel Yellin.
The video provides an excellent overview of blacksmithing techniques. It's also really exciting to see so many smiths working together under the supervision of the late Francis Whitaker, one of America's most famous blacksmiths. Make sure to check out all six of the videos!
