More PRACTICAL IDEAS. Bushings Must Come Every operator hat sweated {or hours over t stubborn bushing that wouldn't budge. Besides being in tight, o bushing is often in t spot you coo'l get at, let alone swing a hammer. That's why I made the puller shown here. Puller is rnnde of two rouoded wedges to fit inside the bushing. Rounded outside has sharp-edged grooves for dig ging into the bashing. By making wedges of tool steel and then hardening and tempering edges, toot remains sharp and digs Into any bushing metaL Left-hand wedge has large hole through center so it does not hind bolt and can move sidawaya, away from right-hand wedge. To use, place puller inside bushing, then tighten nut to expand wedges against bushing's aides. Place yoke and nut over bolt. If lightening nut on top of yoke won't pull bushing out in one piece, I don't know of anything that will do tho job. Another handy gadget for removing o shaft from a gear is made of two nuts and a stud, right-hand sketch.

Wire Wheel Cleans Taper Plug* Old Boiler Makes Feedwater Filter When our load doubled last year, we had to put an extra boiler into service. Then we used twice as much cylinder oil as before. Strain was too much for filter. We got oil back in the boilers. At first It looked as though we'd have to change the filter chemical more often, but that was an expensive job (12 bags for CQch change el $20 a bag). We found a way to beat the rap. We took one old condemned boiler and cut it through tho middle. Then wo welded in three bafBe plates, sketch. In two sections formed by baffles, we put charcoal and covered it with screen.
