桿子拆裝後的性能和安全性

桿子拆裝後的性能和安全性/How about the golf club safety and performance after assembling？

現在球桿都有設計快拆的功能，讓大家可以快速更換桿身和桿頭。可以玩很多的桿身和桿頭。不像以前需要整支桿子拆掉再換其他桿頭或桿身來用。當然有沒有快拆都不會影響玩家和球友們玩其他球桿的熱情。但你心裡一定有個問題就是：桿子拆裝是否對桿子的性能和安全有影響？很多球友或技師都說沒問題！但真的沒問題嗎？

有個基本觀念大家需要瞭解，只要桿子有拆過再裝起來，不管是否原本的桿頭或桿身，都一樣會有差。差在於回饋和擊球結果。所以如果你喜歡你現在的桿子，最好別手癢去換其他桿身或桿頭來試。因為感覺是回不來，而且沒有感覺一模一樣的桿子。就算桿頭和桿身或規格都一樣，也不會有一樣的感覺的結果。

所以別相信朋友或技師說；就先拆下來裝別的桿身/桿頭來試看看，不好再裝回去。是可以裝回去但你原本熟悉的手感和結果都會不對。對技師來說，就是一個拆裝的費用，賺點工錢是小菜一碟。但對你來說損失就慘重。因為感覺和結果是回不來。而且很多技師都是組裝師，不是訂製師。

2者的差別在組裝師就是把桿子給維修、組裝和保養的工作。對於桿子特性或球友適合什麼桿子，或桿頭或桿身的特性他們基本瞭解不多也不深。而要把桿子裝回去是OK但結果和手感只能做到相似，無法複製。因為這當中有很深的學問，才能把桿子做到相似的感覺和結果。

要把桿子做到相似的手感和結果，需要考慮到這些因素和要件如下，桿頭配重、桿頭重心、桿身重心、桿身重量、桿身硬度和整體規格。這些東西需要有對材料、物理、和機械等基本原理，還要對桿頭、桿身有一定的瞭解深度和廣度。也就是說要摸很多不同的產品，需要瞭解產品的特性和回饋，才能選對產品來得到期待的手感和結果。

Nowadays there are many woods featured with interchangeable sleeve that is able to change the shaft and head easily by golfer. With this feature, we can simply change different shafts or heads to play and enjoy the differentiations for convenience. However, if you are the advanced golfer who likes to change different shafts or heads with your woods, you might question if I pull out the shaft and install the different shaft, is it safe to play? Will the performance be good?

Or you want to install your original shaft once you don't like the new shaft. Does the driver keep the same feedback and performance? Honestly it wouldn't be able to have the same feel and performance as you was playing before. Why? there are so many issues and elements will make the driver/wood perform and feel differently once you assemble it.

If you let the clubmaker work on your golf club's assembly, you would not get the same feedback and performance back. Since he is only capable on golf club maintenance, repairing and assembling. he is unable to know the shaft, head profiles, and further for the material, dynamics and machines.

For me I can only make the golf club back to similar feel and performance, it's unable to match the feel and performance like before. It's impossible to make it. Assembly is simple work but to make the golf club to be similar feedback and performance, it requires to know lots of issues to match the results of feel and performance.

That's why I do not suggest golfers to do frequent golf club pull out and assembly. Since the performance and feel will be different and also the risk of safety issue. If you like your current driver with the great feedback and performance, keep it without making any changes or reshaft. You can buy other one with different setup to try but don't just put out and install. It will damage the driver.

下集開始。

另一個角度看球桿的安全性，一支球桿如果經常進行拆裝，這對桿身和桿頭的頸部和桿面都會有影響。一桿身來說，如果是碳纖維材質的桿身，拆桿身需要對桿頸進行加熱，而這加熱也會對桿身的前端加熱。對於碳纖維材質來說，容易讓材質脆化。就算安全性沒問題，對於手感也會改變是無庸置疑。

桿頸位置加熱，也會讓熱延伸到桿面，所以也或多或少會影響到桿面的擊球手感。所以我不建議桿子經常去做拆裝，因為對桿頭和桿身都不好。就算好的東西經過這樣搞也會虛掉。我自己的桿子通常都是做好就不會再去拆掉。除非有考慮到要拆掉，就會考慮一些方法讓影響減低到最小。

再說到一個重點，就是膠水。高爾夫球桿的膠是A/B膠。也是壓克力膠的一種。需要有2種不同的膠水混在一起才能產生作用。而工坊用的牙膏狀的AB膠，在強度是沒問題，但硬了後比較硬和脆。對於手感和能量傳送上就比較差。不是不好而是便宜大碗的東西，很難在質量和細節去要求太多。

我平均每2年就會試新的膠。好的膠水不只在強度和承載力都會比較高，同時它的韌性也會比較好。而這類膠水小小一瓶就上千塊。所以成本就差很多。好處就是打出來的感覺更順也舒服，膠會把擊球的一些震動給吸收掉，手感提升不少，對能量的傳遞也會更有效。

牙醫補牙的膠我也用過。都是我更多使用的膠的一種。現在好的膠不只要強度、承載力、韌性都要好，還要快乾。工坊牙膏型的膠水要6個鐘頭乾。好的膠多半3～5分就OK。最慢也差不多10分就可以乾。所以桿子不是看外觀，看不到的東西就是技師的硬底子實力了。沒有什麼竅門，就是要多去試、花點時間和錢，不斷的積累下來。

Golf club's safety is important issue. If you always pull out the shaft with the same head or your shaft pulls out all the time, it will damage not only the shaft tip structure and material strongness but the head neck and face. Since to pull out the shaft needs to heat up when the temperature stays the certain degree and time, the epoxy cracks then the shaft can be pulled out.

With such process, the graphite carbon material can not always be heat to certain temperature, the tip will be weakening on the strongness. Some clubmakers tell golfers that it's okay to do the pull out but they do not tell you if you do it frequently, it will have the damage for sure later when you play. That's why my golf club don't pull out, once I set up the whole thing, I only do the adjustment on weights.

Another key is the epoxy. It's extremely important for assembling the golf club. However, the cheap epoxy takes more time to dry and the flexibility is not as good as expensive or high end epoxy. I have been trying so many kinds of epoxies including the dentist using on the teeth repairing. It will increase the epoxy's loading ability and flexibility.

Of course, the durability is better than cheap epoxy. The other advantage for epoxy is the loading and feeling are good. If you would like to make your golf club become smooth feedback, to have good epoxy can certainly help you achieve. Of course, more expensive epoxy is simple be dried without 10 minutes. Lots of tour van clubmaker use such epoxy for their contract players' golf clubs.

In the end, assemble the golf club is ok but if you would like to keep your good feeling and performance golf club forever, it's better to keep it without changing. I know people are always looking for something better, but before you reach the better one, you need to keep the best one with you. If you give up the current one and the next one is not as good as your original, you lose all.
