333 dimples?[edit]

I don't know how they create a golf ball with 333 dimples.

http://www.srixon.com/ball_hrx333.asp

See, there's a @#$! 3-piece ball that has 333 dimples. How could it be possible?

File:Golf ball 333.png
A possible 3-piece mold design? (You can also use cube)

Let's see, a dodecahedron has 12 faces, 30 edges and 20 vertices. Now let:

  • each face has x dimples (not including dimples located on edges and vertices);
  • each edge has y dimples (not including dimples located on vertices, y can be 0); and
  • each vertex has z dimples (z = 0 or 1)

The ball will have 12x + 30y + 20z dimples. And that number has to be 333.

But since 12x and 30y and 20z are all even numbers or 0, the ball could not have odd-numbered dimples unless you want to sacrifice its perfect symmetry. This is ridiculous! This is not logical! It drives me crazy! I can't sleep! -- Toytoy 17:57, Oct 20, 2004 (UTC)

Do not assume that x,y and z are integers. There can be half or third dimples on the faces, i.e. a dimple can be on an edge or vertex. -- Lipi 20:43, 30 January 2006 (UTC)[reply]


"And since there is no dimple located on any great circle"

How can this be? There are an infinite number of great circles through any point on a sphere, so some of them must pass through a dimple. Molinari 19:01, 21 Oct 2004 (UTC)

Sorry for my mistake. -- Toytoy 22:55, Oct 21, 2004 (UTC)
It probably should say "There is a great circle that does not intersect any of the dimples." I have to question the statement: "A golf ball can have not a single dimple at all. But most balls on sale today have about 300 to 450 dimples." This makes no sense.
There are multiple great circles that does not intersect any of the dimples. However with certain designs, it is impossible to let a great circle not to intersect any dimple (e.g. a ball covered with densely populated large and small dimples). -- Toytoy 22:55, Oct 21, 2004 (UTC)

Possible advert[edit]

I removed the following text which read suspiciously like an attempt to promote this company's product. Feel free to re-add it with sources. Sandstein 08:48, 16 April 2006 (UTC)[reply]

Some of the new technological advances in a golf ball have hexagonal dimples. This new technology enables the ball to have less drag than the normal dimpled golf balls. The balls have variations on the size of the dimples and also some have deeper dimples than others, Callaway is the main supplier of the hexagonal design golf balls, such as the Callaway HX.

I don't understand why the article should contain this sentence: "One odd-numbered ball on the market is a ball with 333 dimples, called the Srixon AD333." So I removed it. Feel free to re-add it with sources. Freeinfo 22:57, 09 April 2012 (GMT) — Preceding unsigned comment added by 46.31.108.11 (talk)

Dimples and drag[edit]

I've corrected the section which previously said dimples increase drag. The opposite is true (see the link in the article to 'Flight Dynamics of a Golf Ball' - sorry new user no idea how to creat a hyperlink). Same priciple which means that a shark's rough skin reduces the drag through the water compared to if it had smooth skin. MarkW


I agree that the overall drag is lower, but I do not think that dimples allow the turbulent air to attach to the ball. From memory, dimples, trip the laminar flow into turbulent flow earlier. This prevents excessive drag but I am not sure that the simplified explanation I was given is correct. —Preceding unsigned comment added by 124.191.179.252 (talk) 06:02, 9 February 2010 (UTC)[reply]

What's on the inside of the ball?[edit]

Can somebody described the inside of a typical golf ball (ie. what's under the dimpled skin) please. Albatross2147 12:39, 17 May 2007 (UTC)[reply]

Metric vs. Customary[edit]

"Jason Zuback broke the world ball speed record on an episode of Sports Science with a golf ball velocity of 204 mph. The previous record of 302 km/h (188 mph) was held by José Ramón Areitio, a Jai Alai player." 

  Shouldn't the first speed be converted into kilometers, too? Also, I notice how the first speed's main measurement was in mph, while the second speeds main measurement is km/h. Shoundn't they both be the same?

This article contradicts itself[edit]

"...though there have been balls with more than 5000 dimples. The record holder was a ball with 1,070 dimples..."

How can there have been balls with more than 5000 dimples if the record holder only had 1070? 97.80.173.252 (talk) 13:25, 25 January 2011 (UTC)[reply]

Originally read 500 not 5000 before the article was vandalised many moons ago. Reverted now. Thanks, wjematherbigissue 16:29, 25 January 2011 (UTC)[reply]

Used and refurbished golf balls[edit]

Used golf balls are golf balls that have been played, most likely hit out of bounds or into a water hazard, then retrieved, cleaned up and resold. Used golf balls come in different gradings, such as mint (AAAAA), near mint (AAAA) or practice (AA). They are sometimes referred to as "lakeballs". Damaged golf balls with cuts or path marks are also known as "hit-aways" and usually sold in bulk for practice play.

Cleaned recycled golf balls means "Cleaning only". The found golf ball goes through a wash process that allows the recovered golf balls to soak in a cleaning solution. The golf balls are then washed in a specially designed golf ball washer. Some companies remove most or all the clear coat from the ball with a mechanical wet blasting process. This process allows them to get the golf ball as clean as possible before re-clear coating. The objective of the freshly applied clear coat is to provide a consistent and more durable recycled product. Refinished golf balls are processed by stripping, painting and/or clear-coating. The original paint and finish from the golf balls is removed using, a mechanical wet blasting process, the equipment utilized in this process is similar to equipment used in the process of removing mould lines and prepping many new golf balls, before they are painted in the factory. This leaves the original surface to be re-painted, printed and then re-clear coated. This process is utilized mostly for more expensive balls such as Pro V1, HX Tour, and Nike one etc. The same process is also used by some factories to correct misprints. Independent testing has shown that refinished golf balls have only minimal change in flight or roll characteristics, the average player would never feel the differences. Refinishing can not repair cuts, scrapes or path marks. --Netpi (talk) 01:06, 24 March 2011 (UTC)[reply]
