Fig. 39.—Brushing Solder around Dial Ring

Fig. 40.—Tinning Dial Ring

[Figs. 39] and [40] show the method of tinning a brass dial ring. The ring is filed clean and placed on a piece of asbestos board, the flame being applied until the ring is sufficiently hot all round. A bead or two of solder is placed on, and, as they melt, the solder is brushed round as shown in [Fig. 39] with the spirit brush, the flame being applied at intervals to aid the flow.

Fig. 41.—Re-soldering Kettle Spout

Re-soldering Kettle Spout.

—Refixing a spout in a “tinned” wrought-iron or copper kettle. The spout and that part of the kettle which comes in contact with it should first of all be filed bright and clean. Next place the spout in position, apply killed spirits, and hold it over a bunsen flame, as in [Fig. 41], until sufficient of the strip solder is melted to flow around and sweat through to make a strong sound joint. Should any difficulty be experienced in getting the solder to flow readily, apply a little more flux.
