Butt hinges are used when making cabinets and jewelry boxes. Forging hinges is a good project for a beginning blacksmith, because it teaches hammer control and provides an opportunity to practice using a cutting hardy and hot chisel.
Heat a piece of flat 1/8-inch thick by 3-inch wide bar stock to bright orange as seen in low light. Use a cutting hardy or hot chisel to cut the bar as in the diagram.
Reheat bar to bright orange. Place bar on anvil as shown in Figure A and make the first bend by striking the bar at a 30-degree angle.
The bar will look like Figure B once it is bent. The drawing on the right is a front view of the left hinge piece. The right hinge piece will fit into the blue space in the center.
Bend hinge ends around a forming pin as shown in Figure C. This is the first bend.
This is the second bend:
Adjust the pin as in Figure E1 and E2 for a snug fit.
Peen one or both ends of the pin as in Figure F to make an open or closed hinge:
Strike the pin at a 30-degree angle as in Figure F.
When finished, your hinge will look like Figure G:
