The Affect of a Cue Stick's Spine on the Game of Billiards

By Jesse McJames


The cue shaft spine, which is present in all cylindrical articles, refers to the one place in the shaft that bends the least; it is the exact location in the 360 degree circumference of a shaft that will present more opposition than anywhere else in the shaft. Generally, the point that bends the most in the shaft is approximately 180 degree - reverse of to the spine.

The exact same shot, carried out many times, will respond differently because of the shaft's spine. This takes place in play purely because a player turning the billiard cue in his hand, in effect spinning the shaft's spine into a another location with every shot. The cue stick's deflection may be diminished or increase in relation to the alignment of the spine as the cue ball responds to the shaft's stiffness or flexibility at the moment of impact.

In England, snooker, which is played on a larger table with tinier balls and with a number of shots being 13 feet away, will definitely manifest the spine of a billiard cue shaft. Luckily, custom in England stipulates that a flat point be cut into the face of the pool cue at the bottom of the butt. Snooker players always keep the flat point in the palm of their back hand when stroking, which guarantees that the placement of the grain and the shaft's spine will be in the same position with each shot. This manner permits the player to make allowances for the cluster of variations produced by a pool cue with a more significant spine.

If spine placement is not paid attention to when connecting the head of a golf club to a graphite or fiberglass shaft, the club will never play reliably. Each club in the bag will strike the ball differently if the maker does not pay attention to the significance of the spine position. Certain materials, for example tubular steel used in golf shafts, are homogeneous in nature and have a virtually unnoticeable spine; despite the fact that other materials, like graphite or fiberglass, have a significant spine.

In the function of pool cues, most high-quality cue sticks, are made with maple shafts that are much more homogeneous than graphite or fiberglass kinds. Still, every piece of wood will absolutely have a spine that is measurable and noticeable in the hands of a good player.

The stiffer a cue stick shaft is, the greater the variation between the most solid and bendable section of the shaft. Therefore, the billiard cue can respond very differently from hitting a ball with high, low, left or right, simply by the site of the more detectable spine within the billiard's shaft.

A shaft's wood integrity can wear down eventually and the shaft can lose it's ability to snap back in time to adjust for swerve. Subsequently, whilst new the cue reacts as it should but after a while it becomes too flexible. One method to prevent this decomposition, so that the shaft will maintain the correct flex that doesn't disintegrate and will keep it's spring, is to be sure it has six or more parallel grain lines crosswise on a 13 millimeter shaft. This close-fitting grain signifies that the wood was taken from middle of the wood log where the older growth is found. This more mature growth increases the stability of the pool cue shaft. A different manufacturing approach is to in essence generate these grain lines, like what is found in the Black Dot Bullseye shaft by Meucci Cues, in which thirty-five flat maple veneers are laminated as one and then turned round, making more than twenty grain lines that run side-by-side end to end the entire length of the shaft. In Addition, the compact grained shaft has a less noticeable spine.

There is a different method that a number of cue stick builders have attempted to tackle the predicament of the spine being off-center. The goal is to fashion a spine that is dead centered in the shaft, but unfortunately, the very thing they wish to minimize, creates a more definite spine that is off-center. The intention is to cut a shaft into pie pieces and then reassemble it with the grain radiating from the center. Alas, no cue stickbuilder) can retain the apex of the pie pieces in the middle of the shaft for it's entire length. While all through these shafts being turned round, the ends that are in the lathe will be centered, the middle of the shaft is left to it's own position. The method of turning a shaft differs, however nearly all manufacturers turn a shaft four to eight times. Turning a shaft numerous times over days, weeks or months is good and allows movement in the wood and pressure release to thwart warpage. Every turn is utilized to effectively carve out any bend, [however, in the course of this process being done, the middle of the shaft is transferred increasingly to the wall. The pie piece shafts are produced from a single piece of wood and then rolled together and made round with the grain ends divergent. Whereas one can declare that the pie piece shaft is less expected to warp over time, the point is that the less homogeneous spine winds up to be off center.

A player must keep in mind that every pool cue has a spine and no cue builder has been able to dependably offer a pool cue with perfect radial consistency. A accomplished player will be familiar with the response of his equipment and make allowances for the spine of his cue stick. Graphite and fiberglass shafts have the most discernible spine, pie piece shafts have the next, and finally the natural unaltered or flat laminated maple shafts have the slightest.
