Beyond the introduction of the spider line it is unnecessary to mention the various steps by which the Gascoigne micrometer assumed the modern forms now in use, or to describe in detail the suggestions of Hooke, 4 Wren, Smeaton, Cassini, Bradley, Maskelyne, Herschel, Arago, Pearson, Bessel, Struve, Dawes, &c., or the successive productions of the great artists Ramsden, Troughton, Fraunhofer, Ertel, Simms, Cooke, Grubb, Clarke and Repsold.
It depends if you're going for a long shot with power or a short shot with power. I'm going to assume you're going for the long shots. Take about 5 steps back at a 7 o clock aâ¦ngle to the ball. Take 3 quick, tiny steps then take a really fast run up.
The curve ball, or half-masse shot is performed by elevating the butt end of the cue around 45 degrees and striking downward at the cue ball, hitting left or right of center. The two main factors that will determine the path of the cue ball are: 1. How hard you stroke. 2. How far left or right of center you hit the cue ball. With some experimentation, you will begin to get a good feel for how much the cue ball will be pushed off line and when it will curve back in the other direction. Bear in mind, there will be some differences in using a heavier cue ball, such as on a coin-op bar table. It's really a very handy shot.
