CHAPTER XI.

Making a Drawer Pull—Chasing—Making a

Door-knocker—Repousse—Perforated Decoration.

_Exercise No. 7._

Drawer pulls can be of one part, the handle being fastened directly to

the drawer, or they may be of two parts, the handle and plate. The handle

can be made stationary on the plate or movable. In Figure 33 are shown

some hinges, drawer pulls and key escutcheons. The open work is cut out

while the stock is hot, or if light stock is used, it may be drilled, cut

and filed while the plate is cold.

[Illustration: Fig. 33.]

[Illustration: Fig. 34. Fig. 35.]

[Illustration: Fig. 36. Fig. 37.]

The stock used in making a plate for a pull, somewhat like those

illustrated, is represented in Figure 34. After the plate is cut to size,

which is done cold with a hand chisel, the outside surface is hammered

while hot with a ball hammer, drawing the plate a little thinner near

the edge. This hammering gives the surface a rough texture. The edges

are now ground or filed to shape and the holes are drilled as shown in

the drawing. The round holes are for screws to fasten the pull, and the

square holes are to fasten lugs, on which the handle is to swing. The

lugs are shown in Figure 35. The tenon can be filed, the top rounded,

the holes drilled, and the lugs riveted into the plate. When riveting

the lugs, they are caught in a vise, the plate set on and the tenons are

riveted tight into the holes. The square holes in the plate should be

countersunk a little on the back before the lugs are riveted.

The handle is a movable one, and the drawing is shown in Figure 36. The

different steps in making the handle are represented in Figure 37. When

the stock, which should be soft steel, is cut, the ends are heated and

drawn out tapering to ³⁄₁₆ inch at the end. One-and-a-half inches from

each end of the bar is marked with a center punch. The ends are now bent

over ¼ inch, then the bar is bent at the center marks. When the handle is

formed to fit the plate it is smoothed with a file. If desired, a line

can be chased on the handle and around the edge of plate. In doing this

a short, light chisel is used. After lines are traced on the plate with

a slate pencil the chisel is set on the line and struck with a light

hammer; at the same time it is drawn towards the worker with the lead

corner of the cutting edge directly on and above the line.

[Illustration: Fig. 38.]

The chisel should receive rapid, light blows and be continually moved

toward the workman. The lead corner of the chisel should be guided onto

the line while the other corner is doing the cutting. See Figure 38, a

rather large sized drawing of the cutting edge of the chisel. When the

lines are chased with the chisel, they should be gone over again with

quite hard blows of the hammer, forcing the chisel down to make the lines

quite pronounced.

To put the handle in place on the plate, it is heated and sprung into the

holes of the lugs. The last thing to do in finishing all work of this

kind is to heat it to a dark red. All scale and dirt is then scraped off;

when cool, some oil is put on. For this kind of work, machine oil is

good. The reason it is heated to a dark, even red heat is that when cool

the handle and the plate will have the same color and texture.

[Illustration: Fig. 39.]

_Exercise No. 8._

In Figure 39 are shown some hinges, latches and door knockers. Figure

40 is a drawing of a simple knocker. The plate is cut out and the line

around the edge is chased with a tool. The chasing tool is simply a cold

chisel ground to a short bevel and rounded somewhat like a fuller, as

shown in Figure 41. A short chisel is used for cold work and a longer one

for hot work. The chasing can be done while the metal is cold. If it is

to be very deep or wide the plate is heated and a longer chisel is used.

The lug at Figure 42 is made and riveted into the plate. The top of the

hammer is filed to straddle it. A hole is then drilled and a rivet put

thru. Holes are drilled around the edge of the plate for screws or nails.

[Illustration: Fig. 40.]

[Illustration: Fig. 41. Fig. 42.]

In making the hammer a piece of ¾-inch square, soft steel is used. It

is upset on one end to get the stock large enough for the bottom of the

hammer. The bar is then drawn out on the horn as shown at Figure 43. The

top part is formed as shown at Figure 44. Lines are chased on the front

of hammer as shown in the drawing; this can be done after it is formed.

If the lines are to be very deep it should be done while the piece is

straight and heated.

[Illustration: Fig. 43. Fig. 44.]

There is ample room for design in the making of door knockers, both for

outside and inside doors of dwellings. Knocker plates for doors on the

inside of dwellings can be elaborated by a combination of repousse,

chasing and perforated decoration which give a variety of light and

shadow. Perforated plates can be backed up with colored leather or cloth

which gives a very pleasing contrast to the metal.

[Illustration: Fig. 45.]

In Figure 45 is shown an interior door knocker. It is backed up with

colored leather. The plates are made of ⅛-in. thick, soft steel. After

the plates are cut out, the openings are marked with a slate pencil

and gone over with a short cold chisel to mark them. The plate is then

heated, and the part enclosed by the chisel line is cut out. A very

narrow chisel, 12 in. long, is used to do the cutting. The cutting is all

done from the outside. This gives the edge a slight bevel. The edges of

open places are trued up with a file. The openings must not be filed too

exact and smooth. The most essential thing to look after is form; the

work looks best when it shows handwork and is not mechanical.

[Illustration: Fig. 46.]

Handwork is most in keeping with the design and the material. The lines

on the plate are chased with a narrow chisel and the foliated form bumped

out from the back by hammering on the end grain of the elm block. The

hammer that does the knocking is hinged on the top plate so that the

bottom part moves out and in when knocking. Very thin red leather is

glued on the back of the plate with fish glue. The diameter of the top

plate is 4½-in., the bottom 2½-in., and the hammer is 6¾-in. long.

A good method of working out ideas for pieces of this character is to

make numerous rough sketches on paper with a lead pencil, making one line

over another without erasing. When one gets what he thinks is good it is

redrawn and perfected. It may then be worked in the material.

[Illustration: Fig. 47.]

At Figure 46 is shown a door knocker hinged at the top. The plate is one

piece. At Figure 47 are shown the dimensions of the plate. After the

shape of the plate is sketched on the metal, the lines are traced with a

chisel. The open work is then cut out, and the outside of the plate is

cut and filed. The center leaf at the top of the plate is indicated by

forcing the metal down along the top edge of the leaf with a punch, also

at the bottom to form the interlace. The plate should be hot when this is

done. The hammer shown in Figure 48 should be forged from ¾-in. square,

soft steel. The lug shown on the drawing is to be made and riveted into

the top of the plate. The hammer is then placed over the lug, and the lug

is drilled to conform to the drilled holes in the hammer.

[Illustration: Fig. 48.]

The chasing on the plate and hammer is done with a chisel as previously

explained. A gauge should be made from a piece of steel to scratch the

guide lines on the plate for the chasing as shown in Figure 48. These

lines are then cut with the chisel.
