hown in the figure. Then rasp the edge off about 1/8
inch as shown. Take the other piece of pipe and rasp one end as was
done in the cup joint, making it fit into the first piece. Then
place the two ends together and with the bending iron beat the
pipe, making the joint as tight as possible.

ROUND JOINT--45 deg. TO RIGHT

The next position in which the beginner is to wipe a joint is on an
angle of 45 deg. to the right.

PREPARATION.--To prepare this joint, proceed as in the horizontal
round joint. I will enumerate a few of these points. A piece 12
inches long of 1/2-inch pipe is cut off and the ends squared. A
strip in the center, 6 inches long, is shaved clean. Paper and
paste are put over the pipe except 2-1/2 inches in the center.
Grease can be put on the pipe in between the pieces of paper and
will keep the lead from oxidizing.

PLACING PIPE IN POSITION.--There is no need of an elaborate system
of holding the pipe in position. Take a red brick and place the 4
by 8 face down. This will do for the bottom pipe. For the top of
pipe to rest on, place two bricks one above the other; this will
give the correct position. Place the pipe on the brick and with a
ladle full of half molten solder pour a clamp of solder over the
end of the pipe. This will hold the pipe firm for wiping. Place a
catch pan under the joint for solder to fall in.

WIPING.--The method of wiping this joint is practically the same as
wiping the horizontal joint. The catch cloth should be held
parallel with the bench tilting a little from front toward the
back. The ladle is held the same and solder is dropped on as
before. The ladle should be continually moving while dropping
solder, not allowing the solder to drop twice in the same place.
When the solder has been worked around the pipe and is at working
heat, the solder is drawn up with both cloths and the top edge
wiped first, then the bottom edge; the surplus solder is put on the
underside of the joint, and then with three or four wipes the joint
is made symmetrical and finished.

THINGS TO REMEMBER.--

_First_, prepare like the horizontal joint.

_Second_, use brick to place in position.

_Third_, hold tools as in horizontal joint.

_Fourth_, top edge cools first, therefore, wipe it first.

_Fifth_, hold the wiping cloth at an angle of 45 deg. when wiping,
with fingers placed as noted in previous joint.

_Sixth_, make solder clamp for holding the p
