Rob, a hint, from a former horseman. Although they are commonly called "blacksmiths", the people who shoe horses are correctly called Farriers. I will say that all use premade bought shoes. Their propane heated shoeing furnaces have very small & limiting space just enough to heat one shoe for customizing when needed. (My farrier used to draw down tabs called 'clips' which helped holdthe shoe on.) Now, some farriers also hobby at general blacksmithing or ornamental blacksmithing. My favorite Farrier occasionally did ornamental blacksmithing. Farriers are aquainted with each other... may know of someone who would take on such a project.
My re-enactor blacksmith friends, use a coal forge, as does my brother who sometimes covers for the blacksmith at Erie Canal Village. (Rome, NY)
