s. The paste and paper should now be
allowed to dry.

SUPPORTING THE PIPE.--This joint is wiped with the ferrule down on
the bench. A flat pan is laid on the bench and the ferrule stood
upon it. A weight on top of the lead pipe is all that is necessary.
If this does not make the pipe rigid enough for the beginner, then
a support similar to the round vertical joint support can be used.
The beginner is advised, however, to practice the wiping of this
joint with only the weight to hold it in position. The beginner
will then be required to wipe the joint while the solder is hot,
when it does not require a heavy pressure against the solder to
wipe it in shape. These wiped joints should be supported in place
near the furnace that heats the solder so that the solder will be
handy for wiping.

WIPING.--Wiping this joint brings in some of the methods of the
round vertical joint. If that joint was thoroughly mastered, this
joint will be wiped considerably more easily. The ladle is held in
the right hand and the solder splashed on the joint. The catch
cloth is held in the left hand and some of the solder is caught and
brought up on the top edge. The top edge cools quickly as all the
hot solder runs down to the bottom edge and into the pan. As the
solder accumulates on the bottom edge, it is drawn up on the top
edge, and in this manner the top edge is kept hot. When the solder
can be worked freely around the pipe and the edges are hot, the
joint is ready to wipe. The ladle is laid down and the wiping cloth
is taken in the right hand and the top edge of the joint cleaned on
one side. Then the wiping cloth is changed to the left hand and the
other side of the top edge is cleaned. Holding the cloth in one
hand with the index and the third fingers spread to the outside
corners of the cloth, the cloth is passed around the joint quickly.
To get an even and symmetrical joint, it is necessary to make two
or three passes around the joint holding the cloth first in the
right and then in the left hand. The free hand is used to steady
the work. This joint should be wiped very slim to allow room for
the caulking irons to pass by it and get into the hub of the pipe.
Constant wiping on the brass ferrule will result in the tinning on
the brass ferrule coming off. The ferrule will look black when this
happens and will thus be recognized. The wiping should then be
stopped and the ferrule filed
