ion is repeated until the bottom as well as the
top of the joint is heated properly. When the solder can be worked
freely around the pipe, the branch cloth is taken and each side is
wiped from the bottom toward the top. Solder is accumulated on the
top where it is wiped off on the catch cloth and put on the bottom
of the joint. Now reach way around each side and wipe the edge and
body of the joint, a wipe across the top completing the joint. The
bottom can be wiped with a cross wipe also if desired. The top and
the bottom should be identical. Notice carefully the drawing of
this joint and endeavor to have the same lines. The perfecting of
these joints comes only with patient practice. The beginner must
not get discouraged because of a burn or two. As soon as confidence
in oneself has been gained, the possibility of burning the fingers
is entirely eliminated.

BRANCH VERTICAL

The materials, tools, and preparation for this joint placed in a
vertical position are just the same, practically, as those in the
preceding branch joints. One or two points wherein they differ are
mentioned below. To rigidly support the joint for wiping, allow the
run of the pipe to rest on some bricks as before mentioned, with
the branch looking up. Now take a piece of wood and drive a nail
through one end of it about 1 inch from the edge. Let this nail
enter the bore of the vertical branch. The wood is allowed to rest
on the back of the bench or is braced against the wall. Supporting
the pipes in this way will allow the wiper perfect freedom. When
wiping this joint, splash the solder on from the ladle as on the
upright joint. As all the sides of this joint can be seen, it is
not a difficult matter to make a perfectly symmetrical solder bulb.
When the proper heat is gained, the top edge of the joint is wiped
first, then the lower curved edge, using the branch cloth. The body
of the joint is then wiped and the joint finished with a cross
wipe, if necessary.

BRANCH HORIZONTAL

The next position for this joint is to have the branch pipe
horizontal and the run vertical. The materials, tools and
preparation for this joint are the same as for the preceding ones.
The supporting and wiping differ a little.

SUPPORTING.--One end of the run is placed on the catch pan. The
other end is held in place the same way as the branch was held in
the preceding joint. If the pictures of this joint are carefully
looked over, the methods employed to hold t
