Pour also an inch or two up the soiling, as shown at E to make the pipe of proper temperature, i.e., to the same heat as the solder. The further, in reason, the heat is run or taken along the pipe, the better the chance of making the joint.
Fig. 160-a.
Keep pouring and with the left hand hold the cloth C to catch the solder and also cause the same to tin the lower side of the pipe and to keep the solder from dropping down. This cloth, so important in joint making is elsewhere described. By the process of steady pouring the solder now becomes nice and soft and begins to feel shaped, firm and bulky.
When in this shape and in a semi-fluid condition quickly put the ladle down, and instantly with the left hand shape one side of the joint always beginning at the outsides, or at that part next the soiling; then take the cloth in the right hand and do the other side, finishing on the top; a light run of the cloth all round the joint will, if the solder has not set and you have been quick with your work, give the appearance of a turned joint. After a little practice the joint may be made without changing the cloth from one hand to the other.
The secret of joint making is getting the lead to the heat of the solder and in roughly shaping the solder, while in the semi-fluid state.
Good mechanical fitting is the result of two things—good judgment and a delicate sense of touch.
