- First, materials—18 inches of 11⁄2-in. lead pipe.
- Second, use of tools.
- Third, keep bending irons away from the wall of the pipe.
- Fourth, make a good collar around the opening.
- Fifth, make a tight fit with branch and run.
- Sixth, hot solder will quickly burn through the lead.
- Seventh, use branch cloth for wiping.
- Eighth, cut out paper for joint even and symmetrical.
BIB
This joint is another brass to lead, and is the last single joint to be wiped in this course of joint wiping.
Materials Needed.—The materials required for this joint are as follows: 10 inches of 5⁄8-inch extra strong lead pipe; one 1⁄2-inch brass sink bib for lead pipe; one pot of solder, paste and paper, 1⁄2 and 1⁄2 solder,
catch pan, and supports.
Tools Required.—The tools required for this job are the saw, rasp, tap borer, bending irons, file, ladle, wiping cloths, shave hook, knife and rule, soldering iron.
Preparation.—To prepare the lead pipe after cutting from the coil and squaring the ends with the rasp is very similar to the 5⁄8-inch branch joint. The center of the pipe is marked and a hole is made in it with the tap borer large enough to admit the bending irons. The hole is enlarged with the irons. A good substantial collar is made around the hole to hold the bib in place. One and one-eighth inches are marked off on each side of the branch and an easy curve connects the two. The paper is then cut out and pasted on the pipe after it has been scraped with the shave hook.
