HOW TO MAKE THE PIN HOLDER
Material: Copper, No. 24, 3⁄8 in. square to make the flat disc. Copper No. 24, 3⁄8 in. length and about 5⁄16 in. wide to make the cylinder.
With a pair of dividers draw a circle 3⁄8 in. in diameter. Cut out the circle. Place this little disc on the flat end of the hard wood block and with a punch make a hole 1⁄8 in. in diameter in the middle of the disc. On the same end of the block, file (using round file) a groove right across the corner, about 1⁄8 in. deep. Place the small piece of copper (3⁄4 × 5⁄16 ins.), over the groove. Take the steel wire belonging to the hat pin and place it on top of the copper and over the groove. With the hammer, strike so as to drive the pin, and at the same time the copper, into the depression. The copper sinks into the groove and the two sides lap up on each side of the pin. Drive the two sides down until they lap around the wire, the edges meeting. This makes a copper cylinder which fits exactly around the wire of the pin. Take the cylinder off, fit it into the holes of the small disc. Wash the two pieces with a borax solution, place a little solder on, and solder the disc to the cylinder. After cooling the piece in water, shape the disc so that it fits the under side of the hat pin top. Polish the end of the wire pin with an emery cloth, also the top of the pin holder and the inside of the hat pin top. Push the wire into the little cylinder so that it comes flush with the disc.
