Bending a bar

By using a clamp to hold the meal, and strike the metal on the round edge of the anvil using a hammer.

Drawing down

To make a round bar pointed
Hold the bar at a slight angle to the anvil face and hit on one side, the anvil face flattens the other side

Turn the bar 90° and hit again to make the point square in shape.

Hit each corner of the square shape to turn it into an octagonal shape

Continue turning the bar and hitting the corners until the point is round in shape.

Upsetting

the process of thickening the metal by gripping the metal on the leg vice, and then to hit the top with a metal mallet

Twisting

Heat the bar to a bright red and then grip it in the vice and slide on a special twisting tool, or use a large tap wrench.

Forging a loop

Bend the length of the loop circumference over the rounded edge of the anvil.

Start the curve by hammering it over the anvil beak

Work towards the end of the metal to complete the curving

Close the loop by tapping it with a hammer on top of the anvil face

Scrolling

To make identical scrolls a master scroll is used. The metal is heated to bright red in a forge and then tightly wrapped around the master scroll. To stop the metal from slipping the end is prepared by forging the end into a hook shape
