Coil winding is a process used to wind metals into coils for further use in various appliances, furniture and electric devices. A coil winding machine is used to properly wind coil to the correct diameter and size of the coil desired. You can build your own coil winding machine to wind coils for experiments and crafts whenever you need.

Use the saw to cut the 2 inch by 6 inch board into a base that is 3 feet long. The base will support the coil winding machine.
Form upright supports for the machine by cutting the 2 inch by 4 inch board into two pieces, each 8 inches in length.
Place one 2 inch by 4 inch upright approximately 6 inches from one end of the 2 inch by 4 inch board. Use a pencil to mark the perimeter of the 2 inch by 4 inch piece on the other board. Repeat the procedure with the 2 inch by 4 inch piece, approximately 6 inches from the other end of the 2 inch by 6 inch board.
Insert a drill bit of the same diameter as the wood screws in the drill. Drill a pilot hole in the centre of the perimeter markings on the 2 inch by 6 inch piece.
Insert a drill bit of the same diameter as the steel rod that will serve as the mandrel. Drill a hole into the top of each 2 inch by 4 inch piece, approximately 1 inch from the top.
Attach the 2 inch by 4 inch pieces to the base of the 2 inch by 6 inch piece with wood screws. Position the 2 inch by 4 inch pieces so that the hole is at the top of the pieces.
Place the steel rod in the vice with 5 inches of the rod protruding above the vice. Secure the steel rod in the vice by tightening the vice. Use a hammer to bend the rod at a 90-degree angle.
Loosen the vice and pull the pipe from the vice slightly so that there is a total of 10 inches out of the vice with the bent section. Bend the end of the rod at a 90-degree angle with the hammer so the pipe now forms a "Z" shape with one longer end. The shorter end of the rod will serve as the handle.
Loosen the vice and remove the rod completely. Place the rod into the holes at the top of the 2 inch by 4 inch pieces.
Attach the wire for the coils to the mandrel by clamping the wires with vice grips. Turn the handle on the mandrel to form the coil.
