_Material:_ For bowl, copper 12-3/4 × 6 ins., No. 20. For base, copper
4-1/2 × 4-1/2 ins., No. 20. For handles, 2 pieces or 3 pieces of copper
8 × 1 in., No. 20. Solder.
_Tools:_ Combination stake, anvil stake, shears, drill press, drills,
rivets, shaping hammer.
_Directions--Bowl:_ Bend the 12-3/4 × 6-in. piece of copper into a
cylinder over the combination stake. The two edges should just meet,
and fit perfectly along the line. Scrape inside and outside the joint.
Wash with borax, bind with binding wire, and solder. Be careful to heat
it all over the fire till the solder runs freely and fills every part
of the joint. Cool off, then round it up again in the stake, filing off
the surplus silver solder inside and outside. Hammer the joint down
till flat and true. If carefully done this will show a thin even line
of silver.
_Base:_ 4-1/2 × 4-1/2 ins. Cut a 4-1/2-in. disc. Place the cylinder
just made on the disc, allowing the surplus to extend out evenly all
around. Draw with a pencil the outline of the cylinder on the disc. The
rim must be turned up at right angles to the circle so that it fits
exactly over the cylinder. To do this, place the edge of the disc on
the sharp edge of the anvil stake, driving the edge over. Anneal and
repeat until the sides are at right angles to the base. File off the
top perfectly even, rounding out the edges. This makes a finish and
border to the base. Push the cylinder into the bottom. Prepare, as
usual, for soldering. Be careful to put bits of solder both around the
edge of the turned up flange, and on the inside bottom edge. Heat and
finish.
_Handles:_ Copper pieces, 8 × 1 in. Cut a tapered slip off each side of
the handle pieces, until the large end is one inch wide and the small
end 3/4 in. With dividers draw 1/8-in. line parallel to those sides.
Bend each side back on this line. Shape the handle (see design) over
the combination stake, using the fingers or mallet to do so. The top
of the handles should fit up close against the top of the cylinder and
should extend down about 2/3 of the depth of the bowl. The ends may be
rounded off nicely with the shears, and filed. A 1/8-in. hole must now
be drilled in each side. Place the handle in the proper position on the
bowl. Mark the holes and drill them where the marks are made. Place
rivets and rivet the handles on. A touch of soft solder will help keep
these handles in place and at the same time will prevent any possible
chance for leakage through rivet holes, for where you have rivets you
are apt to have a leak. Clean, polish, and finish.
