_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.
[Illustration]
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.

Now the pin is all ready to solder to the head, but there is great
difficulty in getting it in straight. In order to do this I make a
little device out of copper, which helps me in getting things on
straight. Take a piece of copper 1 in. wide and 5 ins. long. Bend each
end, one 2 ins. and the other 3/4 in., both in the same direction at
right angles. With the shears cut a V-shaped piece in the short end.
This little stand is good for soldering any upright piece to a flat
piece, when they should be at right angles to each other.
Place the top of the pin on the long leg of the stand and, with the pin
in the slot, place in proper position and solder.
