Not illustrated. 1908 edition. Excerpt: ...What is the depth of a V-thread of 2 pitch? Ans. 0.43 inch. Of a United States Standard thread? Ans..325 inch. What must the bore of a hole be to chase for a 2-inch bolt with a 6-pitch, V-thread? Ans. 1.712 inch. What is the diameter of a 1-inch 8 thread U. S. S. thread bolt at the bottom of the thread? Ans..84 inch. If we bore a hole to 1.812 inches for a 2-inch V-thread tap of 6 pitch, how near a full thread will it be? Ans. This allows.094 inch on each side, instead of.144 inch as required for a full thread. CHAPTER XI TAPER WORK Any machinist who has tried to turn a piece of work perfectly straight knows the difficulty of getting the tail center set just right to give exactly the same diameter at each end. But when it comes to setting the lathe for just the right taper, especially without useless trials that take a lot of time, it isn't any easier than turning a piece straight. Next to selecting the change gears for thread cutting, the question of how much to set the tailstock over for a given taper is asked more often than any other. While it is a simpler problem than the other, in some ways it has some points which are not always clear. Measuring the Taper The first thing to consider is just what the taper is, as this is sometimes a point for differences of opinion. Some measure the taper on each side, while the usual way is to take the total taper, as with pipe threads. The standard pipe taper is J inch to the foot, which is the same as Tv inch to the inch, or 1 inch in 16 inches, whichever way you like best. In many cases it is easier to have the taper per inch, but we have to take these things as they come to us on the blueprints or drawings. The amount of taper depends on the diameter at the two ends of the taper part of the bar...
