Bucket Work. The use of the oxy-acetylene torch isfurther illustrated in Fig. 10 in connection with work onthe buckets. These buckets, made in two pieces, carry amanganese-steel lip which is riveted in position as in themanner shown by the buckets that appear in the back-ground of the picture. When the lips become worn theycan l>e removed readily by applying the torch to the rivetheads. Or again, in fitting up buckets and lips the torchis used as in Fig. 10 for cutting the rivet-holes throughthe ^ FlO. 10. .1 TTING RIVET-HOLES IN A BUCKET WITH A TORCH October 22, 1921 MINING AND S< II \ I II |< PR Status of the Metal Mining Industry:An Interrogator) III LEAD ion I: Is lead minx tring by means of tin •ii in ral luw< ring of Hi lion?
