After you have used it for boring all the holes or drillingall the iron on a car, you can pass it to the engineer and hewill find that a round wire brush on a long rod inserted inthe boring machine is the finest flue cleaner he has evertried. The wire brush is revolved rapidly through the flueand the machine reversed in bringing it back, straightensout the brush for another liout.
