How to forge weld

So I am giving a workshop at the National Oregon Trail Interpretive center in Baker City, Oregon on the 12th and 13th of September.  I am going to be teaching the basic class in coal fired forge work with the emphasis on the time period of the overland migration. I hope we have lots of folks sign up and I’d like to do this on a regular basis.  I am trying to help them with building a working smithy at the site of the center.  It is hoped that we can teach there and bring folks in from around the area who are interested as well as federal staff from other centers around the nation.
