Things You'll Need:
- Carpenter's pencil
- 2 1-by-8-by-8 inch pieces of wood
- 1 1-by-8-by-18 inch piece of wood
- Carpenter's glue
- 4 2-inch long, ¼-inch diameter wood screws
- Power drill with drill bit set
- Countersink bit
- Carpenter's try square
- Mild steel rods in diameters from 1/8 inch to 7/8 inch
- 2 pairs of pliers
-
Step 1
Use a carpenter's pencil to make lines 1 inch apart from end to end on the 18-inch-long piece of wood. Make tick marks every half-inch between the lines. This provides you with an easy way to measure any jewelry piece as you work with it.
-
Step 2
Clamp the 2 8-by-8 inch end pieces together. Drill 1/8 inch through 7/8 inch holes 3/4 inches apart, 1 inch from the top edge of the two clamped end pieces.
-
Step 3
Apply carpenter's glue to one end of the 18-inch-long piece of wood from Step 1. Set the 8-by-8 inch end pieces on its 1-inch end so the drilled holes are on the upper edge of the square. Butt one of the 8-by-8 inch end pieces of wood against the glued end and press together firmly. Allow glue to dry. Repeat for the other end.
-
Step 4
Step 4Drill two1/8-inch diameter pilot holes into each end piece and through the 18-inch wood base as shown in the diagram. Secure the ends to the base using 2-inch-long, 1/4-inch diameter wood screws.
-
Step 5
Step 5Use two pairs of pliers to cold bend one end of each mild steel rod into spit handles, with two 90-degree rounded turns. The rods will look like the rod in the photo that accompanies this step. These will be your jewelry mandrels.
-
Step 6
Insert a jewelry mandrel into the correct holes across the jump ring apparatus, as shown in the photo from Step 5. Wrap one turn of your chosen heavy-gauge wire around the mandrel. Turn the mandrel to form a ring. Repeat for the number of rings you need.
