This is an excellent method of bending small pipes. Fig. 42 will
almost describe itself. A is a brass or gun metal ball having a copper
or wire rope running through it, and pulled through the flattened part
of the pipe as shown. It will be quite as well to tack the bend down
to the bench, as at B, when pulling the ball through; well dress the
lead from front to back to thicken the back. I have seen some plumbers
put an extra thickness of lead on the back before beginning to bend.
Notice: nearly all solid pressed pipes are thicker on one side than
the other (as before remarked), always place the thickest part at the
back.
