HI, thanks for taking time to view my post!! I have always been interested in Blacksmithing, but since reading 'The Dream of Eagles' series by Jack Whyte, it has really peek my interest again. Out of curiosity, is it even viable to think of creating a hobby forge? How expensive is it? Can they be effective? I have tons of questions, but that is enough for now. Please direct me to a beginner forum if there is one because I may have over looked it. Thanks kindly, and any thoughts would be great!!!
