Tliis is taken care of by the ball bearing rotary carsshown in Figs. 2 and 6. Superheater flues SA in. in diameter are handled by the sanitniethods, and follow the same course tlirougii the shop as the2]4 in. tubes, the various machines being adjusted to suit thelarger diameter. In cleaning, a))OUt si.\ or seven are placed in. Fig. 5—Outdoor Welding Machine and Furnace for Piecing ShortTubes the rattler wilii a load of 2,4 in. tubes. By this method thesplitting of ends formerly experienced has been eliminated. Steel safe ends Ayi in. in diameter are cut the required length,then heated and scarfed by hand. The flues are cut on the iyiin. end and belled out to receive the safe end. The scarf is thenmade by chipping the outside corner of the belled portion oftlie tube as shown in Fig. 7. This method of scarfing eliminatesthe use of a lathe in the machine shop, so that all work on theflues is taken care of in the flue shop. .X liberal amount ofborax is used while making the welding heat and only one heatis taken, the 4/2 in. ends of the flues being heated only twice
