ROUND JOINT 45 deg.--LEFT

When the preceding joint is well mastered and a number of good
joints have been wiped, turn the pipe on an angle of 45 deg. to the
left.

PREPARATION.--The preparation for this joint is exactly the same as
for the horizontal joint. The beginner should turn back and read
carefully concerning the perfection of the joint. Bear in mind that
the pipe must be correctly prepared or a good joint cannot be made.
The edge of the paper must be cut not torn.

PLACING PIPE IN POSITION.--This pipe can be placed in position the
same as the preceding one. If heavy weights are placed on the ends
of the pipe, a bad habit may be formed by the one learning to wipe.
That is, the habit of pressing hard on the joint when wiping. In
the preceding joint, if the beginner presses too hard, the pipe
will fall off the bricks.

WIPING.--Proceed as described for previous joints. The top edge
must be favored a little. The hot solder will run down to the
bottom edge; therefore less solder should be dropped on it than on
the top edge. When the solder is at the proper heat for wiping it
requires only a light touch to wipe the joint. If it appears
necessary to press hard on the joint to wipe off surplus solder, it
shows that the solder is not at the correct wiping heat.

ROUND JOINT--VERTICAL

PREPARATION.--This joint can be prepared exactly like the preceding
one. In fact, the same piece of pipe can be used throughout. When
preparing this joint the end that is to be on the bottom should be
well covered with paper.

PLACING IN POSITION.--The best way to hold this joint in position
for wiping is to stand the pipe upright on one end with the pan
underneath. A piece of furring strip should be run from the top of
the pipe to the wall. Secure the strip to the wall and drive a nail
through the strip into the bore of the pipe. Place a weight on top
of the strip and the pipe is ready.

WIPING.--The procedure of wiping this joint is entirely different
from that in the other positions. The solder is thrown onto the
joint from the ladle. The catch cloth is held up to the pipe and as
much solder as possible is held on to the pipe. Move the ladle
around the joint, throwing a little solder on as the ladle is
moved. Notice now that all the solder runs to the bottom edge,
leaving the top edge cold. The solder that accumulates on the
bottom edge should be drawn up to the top edge with the cloth.
Then splash more solder on
