Bowling bore technology (primary piece)
From;  Author:Stand originally

Bowls bore is a very main technique, it matters to the technical level of the player to rise, reach primary player the further progress problem henceforth.

Had hit bowls person to know, enter bowling place, a lot of public balls are offerred use, public ball also calls field special ball, the bowling that the everybody on broad sense can use, everybody is on narrow sense inapplicable bowling, show because of it aperture and span are not made according to each specific person.

If lover of a bowling, hit 18 bureaus above every week, with respect to the special ball that should consider to choose an individual, because play bowling,be to use singlehanded thumb, middle finger and ring finger commonly 3 point to holding, and the finger accident of everybody, soft hard, degree of finish, dry wet, size each are not identical, finding a public ball that suits oneself is a quite difficult issue, do the special ball that suits oneself to be able to raise bowls technology level on one hand, master accurate method, can decrease on the other hand get hurt reach finger to be out of shape.

Of course, the change of lover of Cong Baoling ball to the player is not division of a high drill or a the most advanced bowling can change, the individual own technique of the player is the most important. The method of ball and bore is additional forever method, just want to player help of Gao Shuiping a few bigger. As the progress of level of science and technology, contemporary bowling depends on a level to had been inferior to to the individual's technology 7, 80 time, fight each other for the player of curve, the curvature in those days is ability relying on a ball, and can rely on money now, buy curvature through changing ball and bore ability way, and the motivation that what want beautiful time exclusively is pair of him movements finalizes the design.

So how to reach to bore of a ball choose a ball for oneself?

One, bore genre:

Bowling develops relatively maturely in the United States, represent the advanced level of the world, arrive from bowling ability law relevant technology and relevant things. American bowling federation and federation of world woman bowling (ABC/WIBC) it is association of 10 bottles of bowling of international bowling alliance and world (FIQ-WTBA) the attestation country of designation bowling lane and things / area member. International protects couplet is belong to international Olympic committee internationally sports organization, this decided this organizes current amateur athletics capacity.

In American bowling motion has profession and spare branch, go up in relevant technology likewise, differ because of the standard that follow, there also are two important schools on bore technology: Association of political instructor of international bowling brand shop (IBPSIA) reach association of American profession bowling (PBA) .

From bore technology, these two kinds get a law to representing advanced means, but these two kinds of methods do not conflict, because IBPSIA method is to be spare player service, and PBA method is to be professional player service. Their service object is different, this is decided by dozen of law of two kinds of players.

The way is made in amateurish in, the effect of thumb is bigger; And on-the-job course of study makes a way in, its action is lesser. This nods simple distinction, the consideration element that makes go up in bore method is alien bigger, this also is IBPSIA and one of focuses that PBA argues.

In addition, because the research on the base that builds beauty is in Europe to plant comes out method of these two kinds of bore, want to undertake improvement according to the characteristic of Asian ethnic group in some respects consequently, cannot apply mechanically, the flexibility of the thumb of ethnic group of for example Asia is general excel Europe beauty.

The method of article introduction basically is the method of IBPSIA, all be with right hand player below exemple, left hand is contrary.

2, the classification of the ball:

For the development of Cong Baoling ball, material is qualitative on cent is balata, plastic, get together amine fat, active gets together amine fat a few kinds of material.

From the point of the achievement of research, what all sorts of not congener profile pledge is spherical the temperature that arises for an instant with the contact of lane is:

Balata ball 45°C

Plastic ball 60°C

Get together amine fat 450°C

Active gets together amine fat 600°C

If use,get together the ball with amine fat qualitative material, leaving oily woodiness lane, but char of lane surface instant, form a lot of macula.

Of the surface from the ball spend glossily for, bowling cent is reached for smooth face wear arenaceous face, of ball of general light face leave factory polishing uses 600# sand paper, grind arenaceous face ball to use 320# .

According to the state of lane, can use 200# to change the face of the ball to 1500# sand paper, in order to get used to different lane face and player requirement. This provided a space that develops ability adequately for bore division, change the face of the ball with different sand paper, can make the ball of a mediocre performance becomes provide power more.

From ball needle (PIN) with ball center (CG) the distance is divisional: Ball cent is inside ball needle (ball needle and central distance are in 1 1/2 inch inside ——PIN IN) , in ball needle (ball needle and central distance reach 3 inches in 1 1/2 inside ——PIN MEDIUM) , outside ball needle (ball needle and central distance are in ——PIN OUT of 3 inches of above) . To making the player of curve, choose a few outside the ball of ball needle, the space that develops to bore division is a few larger also, can the need according to the player, the ball that makes different style comes.

Generally speaking, of these data distinguishing is enough to primary bore division. The manufacturer of the ball can have a piece of specification to ball other data in ball box, include to carry the data of the respect such as nucleus of heavy, ball, oily course on the head, about their action, be in in advanced piece in, still can show its effect respectively.

3, the foundation that get a ball:

No matter be IBPSIA or PBA, be in follow respective standard, IBPSIA is to establish the standard in ABC/WIBC, namely the demand that the standard —— of FIQ-WTBA balances to bowling weight, this is the standard that the bore division that bears the blame to a bowling must observe, because the player is the client of bore division, it is consumer, the businessman wants to be in charge of to the client, the ball that makes a qualification comes.

The demand that FIQ-WTBA balances to the ball is as follows:

10 pounds (contain 10 pounds) the ball of above, coping and bottom weight are poor (very heavy TOP WEIGHT) in 3 ounce less than; Two side weight is poor (emphasize particularly on SIDE WEIGHT) reach weight of thumb aperture part and finger aperture part to differ (point to heavy FINGER WEIGHT) inside 1 ounce.

8 pounds (contain 8 pounds) the ball to 10 pounds: The top must not be more than 2 ounce again, emphasize particularly on reach point to must not be more than 3/4 ounce again.

The ball under 8 pounds: Very heavy, emphasize particularly on reach point to all must not be more than 3/4 ounce again.

A bowling cannot exceed 5 for the aperture of the purpose with bore, the aperture that is a purpose in order to check 1, the aperture that is a purpose in order to balance 1, every holding aperture can have a steam vent. Because this one bowling has 12 opening at most.

The weight of the ball cannot exceed 16 pounds, hardness cannot under “D”72°.

Above is the law that division of bore of a bowling must remember well in the heart. And of these law fulfil, must have the aid of one billiards balance. There is ball balance in a brand shop is inconceivable, sell the inequity that the client is pair of clients the ball that did not pass ball check, because this has in this respect client,complain the right that reachs claim for compensation. Ball balance is used at ball check not only, and still decide the optimal tool of bore position, about the content of this respect, in in advanced piece in still will discuss.

4, the understanding of angle:

The concept of angle: If broach lies “0” angle, those who point to is broach going up to the center of the ball, if pursue:

Zk1.gif (4665 byte)

0 angle 0 angle

1/2 angle

If broach translation 1/2 inch, extension line of center pointing to aperture and central distance are 1/2 inch, this produced point of view.

Each show Kong Dou is controlled by 4 direction, it is forward, backward angle from fore-and-aft cent; It is angle of towards the left, rightward from transverse cent. If pursue:

Zk2.gif (3444 byte)

Middle finger and ring finger backward

Middle finger and ring finger are forward

Towards the left right

Thumb is forward

Thumb backward

On transverse angle, the direction of middle finger, ring finger and thumb does not have distinction. For example: 1/2 of towards the left inch, point to go up in transverse angle, extension line of center pointing to aperture is in the center of the ball left, the distance is 1/2 inch.

On fore-and-aft angle, the directional as it happens of middle finger, ring finger and thumb is contrary. For example: Middle finger, ring finger is forward 1/2 inch, point to go up in fore-and-aft angle, extension line of center pointing to aperture to deflection of direction of the centre of the palm, the central 1/2 that is apart from a ball inch; Thumb is forward 1/2 inch, it is to be on fore-and-aft angle likewise, extension line of center pointing to aperture to deflection of direction of the centre of the palm, the central 1/2 that is apart from a ball inch. Accordingly, it is forward concept together, and directional as it happens is contrary.

Because middle finger and ring finger are transverse together, if angle is “0” together, inevitable meeting is in spherical next assemble, consequently these two angle are towards the left of middle finger angle commonly, ring finger right, parallel way retains on cross section, the absolute value addition of these two angle is 5/8-7/8 inch between for beautiful, for example middle finger angle is 1/8 of towards the left, ring finger angle is right 1/2, absolute value is 5/8; Middle finger angle is 3/8 of towards the left, ring finger angle is right 3/8, absolute value is 6/8.

The transverse angle of thumb wants to be decided in order to hold round thing, pursue as follows:

Zk3.gif (4150 byte)

Thumb is mid the angle that point to is transverse angle, if point to 1/8 left transverse angle is a thumb 1/8 of towards the left.

5, the understanding of span:

The concept of span is divisional 2 point to, point to half, the element that points to a ball.

2 point to a ball, namely groovy ball, public ball is field mostly this kind of practice, it is to show Kong Er of middle finger and ring finger deep goal points to deep length, this kind of practice applies to linear ball, natural hook ball, reach fly dozen of law of butterfly ball.

Point to half, it is to show middle finger and aperture of ball of ring finger development point to half deep length, this kind of practice applies to linear ball, natural hook ball to reach fly dozen of law of butterfly ball.

Point to a ball, it is to show middle finger and aperture of ball of ring finger development point to deep length. Span is the longest, agree with dozen of curve, law of this kind of holding is most a kind of method of save labour, holding is consequently opposite heavier, be in commonly 13 pounds above, control the whirl of the ball more easily at the same time.

General span component reachs thumb to the span of middle finger for thumb the span to ring finger. The thumb of average person should grow to the span of ring finger at the span to middle finger.

1, the 2 measurement that point to a ball:

Point to a place from thumb (if insert,point to Kong Zhong and spherical neat niche, with natural state had better) quantity to middle finger the 2nd joint falls (to direction of the centre of the palm) 1/4 or 3/8 inch place come for thumb namely the span of middle finger; Measure to method of ring finger span also identical.

2, point to the measurement of half:

From thumb place pointing to a root is measured to middle finger and ring finger the 2nd joint is in. Subordinate list was offerred 2 point to reach show half span and angle contrast watch, can define corresponding point of view pointing to aperture according to measuring the span that go out.

5

Backward 3/16 comes 5/16

4

Forward 1/8

5 1/8

Backward 1/4 comes 3/8

Note: What this angle points to is middle finger and angle of ring finger around, thumb around angle is “0” , this watch suits to be not fly the practice of butterfly ball.

3, the measurement that points to:

From thumb place pointing to a root is measured to middle finger and ring finger 2 articulatory 1/2 are in the first articulatory pass an imperial examination, according to player level rise, stand by the position that the first joint manages stage by stage, achieve the 5/16 below the first joint inch place for beautiful.

Span is an important data, the points to aperture angle that it decides: Span is shorter, angle is jumped over should forward; Span is longer, angle is jumped over should backward.

In the meantime, according to the hand dry wet, soft hard, accident is again diagonally degree undertake fine tuning, point to the angle of aperture finally each certainly.

Subordinate list offerred the span that points to a ball and angle to contrast watch.

Note: What this angle points to is thumb around angle, middle finger and angle of ring finger around are “0” , span change 1/8, angle change 1/16. This watch suits to be not fly the practice of butterfly ball.

6, the understanding that points to aperture:

Choosing right size pointing to aperture also is likewise serious problem.

Generally speaking, after defining the deepness kind that makes a ball, and quantity hand dish or model ball will measure the volume that points to aperture:

1, middle finger and ring finger measure the natural size in the limit of before measuring span to nod with showing Pan Kongneng is passed;

2, the natural size that thumb reachs point pointing to a root with pointing to dish of aperture is beautiful.

Natural meaning is finger does not suffer those who show Pan Kongji is pressed the smallest state.

Master middle finger and ring finger moderate commonly to abecedarian, thumb magnifies 1 reach 2.

The deepness that points to aperture does not exceed 2 inches for middle finger, ring finger commonly, big toe does not exceed 3 inches.

7, the firm position that get a ball:

Every bowling has him leave factory number, if the Id of colleague is same, every ball is different, the around is a ball commonly center position in number namely CG, still have ball injection in addition (PIN) , for diametical 1/4-1/2 inch the with spherical and different color dot of a size.

The groovy position that get a ball:

The center that center establishs in the ball (CG) go up, if the ball has ball injection (PIN) , put ball pin on the direction of ring finger, if hit curve, with 30°- 45°direction is advisable (little finger direction) .

From theoretic tell, the position that becomes hole can be in the random of the ball locally, inside the balance range that wants a ball to be able to accord with a regulation only, the center that general and safe method is choice ball (CG) all round the method that is center, because be the position that the weight of the ball amasses commonly here, it is the coping of the ball namely.

If the position of the design, exceed the regulation of the balance, can use the method that adds dozen of balance aperture to solve, balance Kong Congli to talk on can put in aleatoric position, should not be only in ball course namely it is OK that the ball does not press balance aperture in scroll.

Curve and fly the advanced method making a ball of butterfly ball is around ball needle (PIN) undertake, in in advanced piece in can have detailed treatise.

8, the lineation of the ball:

With visual the center of the ball (CG) the font of upper part to for direction, do to pass center of perpendicular font linear, upper part is the position of set middle finger and ring finger, lower part is the position of set thumb, from center the quantity produces thumb to be the edge outside middle finger aperture to the 1/2 of middle finger span, decide the edge outside ring finger and thumb with manage.

About the bridge: Middle finger is the bridge with what the distance between ring finger says, the physiology characteristic from the person, it is closer better, but the problem that the capacity poses the bridge. Bridge of bowls manufacturer proposal is in 1/4 inch above is safety, short be apart from hereat cause the bridge not to belong to quality problem, if add fingertip bridge,cannot be less than 3/16 inch.

After affirmatory good span, in central line two side middle finger and ring finger place do 1/8 of two distances central line inch parallel, the distance of these two parallel is the bridge namely.

According to the lineation of the ball, drill middle finger and ring finger hole, fore-and-aft it is the edge outside showing aperture is fore-and-aft with span line, transverse it is horizontal stroke pointing to aperture with the parallel of the bridge outward edge; Get thumb to be center with central line, span line is the edge outside pointing to aperture.

9, bore measure:

1, the kind that makes a ball certainly according to the need of the player;

2, measure a player point to aperture, span;

3, showing Kong Biaozhong records concerned data, undertake adjustment according to player circumstance;

4, choose to become opening position on the ball and underline;

5, the basis underlines the position, whether to undertake checking inside formulary limits to the balance of the ball;

6, undertake bore to the ball, get middle finger and ring finger a side first, or get thumb a side first but;

7, after getting a side, remeasure span, if error reentry is adjusted all right;

8, the drill that completes another side;

9, let a player undertake to the ball comfortable match, what point to aperture according to inserting is difficult use drawknife easily to undertake adjustment to pointing to aperture;

10, after adjusting an end, with sweep an edge implement Kong Bian middling finger grinds divide evenly;

11, teach a player how to use pushball correctly.

10, last word:

Above is the content that he suggest to master to bore abecedarian, to among them a few content, in in advanced piece the lieutenant general is discussed in detail. Much practice is the key that improves the technology that get a ball.

The bore division that welcomes broad bowling lover to have practice experience especially offers criticism and make a comment or criticism to the article.
