_Material:_ 3 pieces of copper, 6 × 6 ins., No. 20. One piece of round
rod copper, 1 in. long. One piece of copper, 12 × 1/4 ins. (for rim).
Solder.
_Tools:_ Hard wood block, round head and anvil stakes, combination
stake, shears, dividers, planishing hammer, raising hammer, and shaping
hammer, files, emery cloth.
_Parts:_ Bowl, stem, base, lid, ornamental top of the lid.
_Directions:_ Make a working drawing (full size) on drawing paper, plan
and elevation.
_Bowl:_ Take the 6 × 6-in. piece of copper. Cut out a 6-in. disc.
Drive the bowl up as you did the copper bowl. It should be the same
shape as the copper bowl. Do not flatten the bottom. The drawing shows
that the bottom should be rounding, to fit the stem.

_Stem and base:_ Take another piece of 6 × 6-in. copper. Cut 6-in.
disc. With the dividers make a 1-in. circle in the centre of the disc.
This inner circle must be beaten up until it becomes the stem. To do
this place the disc on the round top stake, with the marked circle
touching the edge of the round top. Strike with the raising hammer just
above the circle line, turning the disc each time. When you have made
one turn of the disc, repeat this twice, hammering just above the part
driven up before. Keep repeating this until you have reached within an
inch and a half of the outer edge of the disc.

The drawings numbered 1, 2, 3, 4, show the steps in the working up of
the copper disc into the stem.

You now have a bell-shaped piece. Anneal the metal and repeat the
hammering, beginning at the same place and working up to the same
place as before. Anneal whenever the metal seems springy and keep
working until the stem is tapered about 3/4 in. at the small end,
gradually widening into the vase. Place the bell-like stem on the
table and flatten it so that it lies perfectly smooth, with the stem
perpendicular to the base. Find the centre of the bowl, describe a
3/4-in. circle. Scrape both the circle and the small end of the stem.
Turn the bowl upside down, place the stem end of the base on the bowl,
and solder in the usual way.
_To make the lid:_ Take the 6 × 6-in. piece. Cut a 6-in. disc. Find the
centre. Drive the centre down by using the small end of the planishing
hammer. This makes a cone-shaped centre, with the sides gradually
widening to the edge of the lid. The highest point of the cone is one
inch above the level of the lid. Place the lid on the table and tap
gently on the outside until it lies flat. Take the small 3/8-in. piece
of round rod, file a small shaped ornament (to taste) on one end of the
rod and a shoulder on the other end. Drill a hole in the cone-shaped
part of the lid, push the rod 1/8 in. through this hole and rivet it on
the inside.

_Rim:_ Strip of copper, 12 × 1/4 ins. Bend it into a circle just to fit
the outside of the lid. Cut off the proper length and solder. Make it
perfectly round and perfectly flat. Place the lid on the chalice bowl
so that it overlaps a little all around, evenly. Draw a pencil line all
around the edge of the bowl on the under side of the lid. This is where
the rim is to go. Before soldering, test, by placing the rim on the
face of the lid. Any openings seen must be closed by pressing the rim
down to the lid. Bind tightly with binding wire, scrape, and solder.
File and finish.
