The end of the brass bib is filed bright and tinned with the soldering iron and 1⁄2 and 1⁄2 solder. Before the tinning is done, paper is put on the brass, leaving only 11⁄8 inches exposed. The tinning must be thoroughly done, or it will come off and have to be re-tinned.

Supporting.—The bib is fitted into the lead opening and the collar is forced against the bib to hold it in place and prevent any solder from leaking through into the bore of the pipe. The bib must not extend too far into the lead pipe or it will obstruct the flow of water. The lead pipe is laid on two bricks the same as the round joint. The bib is laid on an angle of 45° pointing away from the wiper. Some bricks can be piled up to the right height to hold the bib in place and a solder strap can be made to hold it steady. The lead pipe can be held steady by weighting each end. The catch pan is now placed under the joint and everything is ready for wiping.

Wiping.—When the solder is hot, getting the heat on the pipe is started. Solder should be dropped oftener on the brass bib than on the lead pipe. It takes more heat to heat the brass thoroughly than it does the lead. If this is followed out, little difficulty will be had in getting up the heat and in wiping. Use the branch cloth for wiping and make sure that all edges are perfectly cleaned before making the final strokes. As this is the only position that the joint will be wiped in, practice should be continued until perfect joints can be obtained.

Points to Remember.

  1. First, materials needed.
  2. Second, tools needed.
  3. Third, use tap borer.
  4. Fourth, enlarge hole with bending irons.
  5. Fifth, make substantial collar around the opening.
  6. Sixth, paper the lead.
  7. Seventh, file the bib, then paper.
  8. Eighth, tin the bib.
  9. Ninth, place in position and wipe.

DRUM TRAP

The making of the drum trap will bring out the skill of the beginner. The entire trap is made of lead pipe. The lead will require a great deal of handling. Therefore, care must be exercised in all operations to turn the trap out in a workmanlike manner.
