The Tee Joint on Round Pipe.
Fig. 35.—Making a Tee Joint on Round Pipe.
With a pair of compasses set the diameter of the pipe that it is desired to insert, and strike a circle on the pipe which is to receive the tee. With a tap borer, or any other device, cut out a circle of lead, leaving about ¼ inch to turn up. Then draw this remaining lead up by means of a bending iron and a heavy piece of iron, such as a chisel, as shown at B in Fig. 35, until the hole is large enough to receive the piece intended for it, the end of which should be beveled with a fine rasp, as shown at a. The lead should then be dressed back against the pipe, after which remove the piece and shave clean, and proceed to burn as described for the lap seam on round pipe, and as shown in Fig. 36. Care must be taken in dressing up the lead flange to dress it slowly so as to avoid weakening the lead.
