en against it with the
bending irons. The run is now cleaned with the shave hook for about
3 inches each side of the center. The paper oval cut out is now
pasted on the joint. The paste and paper are then allowed to dry
before they are handled further.
SUPPORTING.--The supporting of this joint, which is placed with the
branch on an angle of 45 deg. pointing away from the wiper, is not a
difficult matter. The beginner can use his own ingenuity for
supporting the pipe if conditions do not warrant the using of the
methods previously described.
WIPING.--The solder should now be tested for heat. If the solder is
at the proper heat, the ladle is taken and heated. Take a ladle
full of solder and drop the solder on the joint. The lead of which
this branch joint is made is considerably lighter than any lead
that has been used before. Therefore, the beginner must drop the
solder on carefully, making sure that the solder is not dropped on
the same spot, for a hole can be burned through the pipe very
quickly. The ladle must be kept moving, then the solder will not
burn through the pipe. The heat is got up on the pipe by dropping
the solder on the run and on the branch, catching the surplus
solder on the catch cloth and heating the under side of the joint
with it. To form the joint, distribute the solder and then wipe it
into shape. Notice that I said wipe it into shape. A beginner is
very apt to try to push or poke it into shape. This must not be
done as it has a tendency to make the joint lumpy. All the edges
are wiped off clean first, then the body of the joint is shaped and
wiped. When forming the joint, be sure that the bottom and the top
are symmetrical. Do not have one-half larger than the other. The
last wiping strokes are made swiftly and rapidly. If the wiper will
watch his movements and note the results and then try to improve
them, keeping in mind that a symmetrical joint is wanted with thin
edges, perfection in wiping will come much more quickly than if no
attention is paid to the strokes made when wiping.
BRANCH JOINT WIPED FLAT
The materials required for this joint do not differ from the
preceding one. If the pipe used for the branch joint at a 45 deg. angle
is in good shape, it can be used for this joint by simply changing
positions. The tools needed will not be any different. The ladle
and the wiping cloths, of course will be required. A pair of pliers
can be used to advantage in picking up the hot solde
