Placed in the lathe on this spindle, the whole thing may he finished off in a jiffv, to the required dimensions, without Further ado. actually ready for immediate use. But this hastily-put-together product, after all, is a poor excuse for a real cone pulley. Built of solid blocks, these will be more or less subject to shrinkage, while the chances are that one or more will split in course of time. There is really nothing to prevent these undesirable results in a pulley thus shabbily and hurriedly thrown together. Every once in a while it will need retouching to avoid a wobbling motion of the belt or uneven running of the machine, two extremely objectionable features in any kind of a pulley. Now, to build a real strong, serviceable cone pulley, such as will last a lifetime, if need be, an entirely different plan from the foregoing must be adopted. In this instance, the pulley will need to. Fig. 2—The Finished Pulley. be built up gradually, on a regular raceplate, and of thin material. In fact, each step should consist of no less than three separate layers of segments, each course, in turn, being firmly glued and nailed onto the other. To be sure, this work is slow, tedious and runs away with con- siderable time, but when done the result will more than repay all extra trouble. An article will be produced at once solid and un- shrinkable, destined to stand the wear and tear of many years of hard
