1. Forging a "simple scarf" (a short taper) at the far radiused edge of the anvil. | |
2. The flat side is untouched by the hammer and the corners are slightly chamfered. | |
3. The piece is forged over the horn of the anvil. Stock is 3/16" x 1 1/4". |
|
4. "Backing up" the bend on the anvil face. |
|
5. The scarf point just touches the parent stock; flat side of scarf faces the stock. |
|
6. A combination drift/mandrel is inserted at the far end of the bend. |
|
7. The strap is lifted to let the mandrel roll away from the smith. |
|
8. The smith lowers the holding hand as he/she "traps" the mandrel with half-face (overhanging) blows. The scarf is up; the loop hangs down. This is a good setup for welding. The hammer is an old three pound Channellock. |
|
9. Twenty Mule Team Borax is applied inside and outside the barrel. |

10. More Twenty Mule Team Borax |

11. Welding the barrel with half-face blows at a sweating heat. |
|
12. Welding the edge shuts. |
|
13. The drift, tapered at both ends, is once again placed through the eye of the hinge. |
|
14. The drift is driven into the barrel on the anvil face and then moved to the pritchel hole and driven through. |

15. Starting to work on the traditional taper at the end of the strap hinge opposite the barrel. | |
