INK POT.

This exercise is carried out as follows: A form is first raised like the

lower part of the pot inverted, which is nothing more than a bowl so

far. A hole with a diameter a little less than the diameter of the ink

well is then sawed with a piercing saw in the bottom of this bowl, as at

A. After this a circular piece of metal is cut equal in diameter to the

top of this bowl plus 1/4 of an inch, and soldered on G. By making this

piece 1/4 inch greater than the diameter of the bowl, the soldering

process becomes much easier. After the soldering is finished, the

projecting edges may be filed off to the edge of the bowl. The bowl is

then inverted so that it rests on its greatest diameter H, and it

becomes an ink pot.

[Illustration: FIGURE 29. Dapping tools in use.]

The cover, J, is made by taking a circular piece of metal and raising

the sides in the same way as in the bowl except that the design calls

for the sides at right angles to the base. The curve is obtained by

placing it on a sand bag and driving it out from the inside to the

required height. From a strip of copper 20 gauge and 3/16 inch wide, C,

make a ring, D, equal in diameter to the inside of the cover. Solder the

ends of the ring together and, after shaping it over a circular stake,

fit and solder it to the base, as shown in the section at E.

[Illustration: PLATE 43.]

This keeps the cover in place. The knob, K, on the cover is made of two

hemispheres, L, by use of the dapping block and tools, Figures 7 and 29.

The two pieces are soldered together, filed or finished about the joint,

and soldered to the cover, F. After dipping the different parts in the

pickle, then washing them in clean water, and doing a little filing here

and there about the joints to remove surplus solder, the ink pot is

ready for finishing. This may be done by polishing, bronzing, or

oxidizing.

The ink well proper should be made so that it may be removed. It should

be of glass or some other material easily cleansed.

SEALING WAX SET.

THE WAX POT.

The wax pot is raised into shape as described in Chapter VI on raised

forms. Instead of cutting the top off level, a nose is formed as shown

at A, Plate 45, which will pour well. A handle is designed, sawed out,

and riveted on at the position indicated at B.

THE LAMP.

The body of the lamp is made by raising a bowl to conform with the

design; after cutting a hole in the bottom it is inverted, C, and the

bottom is soldered on at D. A shallow cup is raised, E, a hole cut in

the bottom to allow for the lamp proper, and soldered to the body. Legs

as shown at F, and held together by a strip, H, are riveted to the side

of the body at G; on these the wax pot rests. The lamp proper or alcohol

well, which is filled with asbestos, is raised with the edges turned

out, as at N, which hold it in place as shown in the section at J. The

part at K serves as a burner and is placed loosely in the cup, E,

allowing its removal at any time.

SEAL.

A monogram, letter or design of some sort must first be decided on. When

this has been done, the design is transferred and scratched on a piece

of 22 or 24 gauge copper. If the design has a right and wrong to it, the

reverse should be transferred to the metal so that, when stamped, the

right side will appear. The copper is then placed on the pitch and when

cool enough to work upon, the lines are followed with a chasing tool,

sinking them to the required depth. Care must be taken to avoid sharp

edges or any undercutting, if the seal is to free itself easily from the

wax. A handle for the seal may be made of wood as shown on the plate;

the seal is cut and attached as shown at Section on L. M.

WATCH FOB.

There are many ways of making watch fobs. A very simple one is made as

follows: First make a drawing of the fob with some suitable pendant as

at A, Plate 46. The pendant design is next transferred to a piece of 12

gauge copper, then sawed out and filed into shape. This must be done

with perhaps more care than on larger work as it is to be more closely

scrutinized. The parts of the fob must be made to conform with the width

of the ribbon that is to be used. A bar must be made for the top, wide

enough for the ribbon to be passed through and fastened. This bar is

made by cutting a slot in a piece of metal of the same gauge as the

pendant, or by bending a piece of wire around a piece of metal about

1/16 of an inch thick and the width of the ribbon, making the ends meet

in the centre of one of the long sides. If more than one of these pieces

is needed, the wire is wound around the metal as many times as there are

pieces required and sawed apart. The ends are then bent to come in line

with each other and soldered. The piece is again placed over the metal

and, with a rawhide hammer, worked into shape. The links that connect

the bar and the swivel are made as all links are made. Take a piece of

iron or steel wire the size required and also a piece of copper; place

one end of the steel wire and one end of the copper wire in a vise so

that the steel wire stands vertical. Then wind the copper wire around

the steel wire spirally with as many turns as there are links required.

Now take it out of the vise and slip it off the steel wire, which leaves

it in the shape of a spring. Hold it with the thumb and forefinger of

the left hand and, resting it against the bench pin, saw the links off

with a fine saw one at a time until there are as many as needed.

One of these links is soldered to the bar that holds the ribbon and one

to the top of the pendant; the others are linked together to form the

short chain at the top. To connect the pendant to the ribbon, two larger

links are needed which are made in the same way as the small ones. All

the links may be soldered or not. The links that are soldered to the bar

and to the pendant should be filed flat a little to make the point of

contact greater. This insures a more secure joint. When soldering such

small pieces the charcoal block is indispensable, for depressions are

easily made in it where necessary. The parts are placed on the block in

position and a small mouth blow-pipe is used; with this the flame can be

more delicately applied.

[Illustration]

When the different parts are completed, they are pickled, rinsed, dried,

and polished, and then put together with the ribbon.

Fobs are sometimes made entirely of metal as B, Plate 46. In this slots

are sawed in three or more bars of metal which are linked together with

links made from the same thickness metal as the bars. The pendant and

the swivel are also connected with the same kind of links.
