Increasing the Pre-Bend on pole manufacturing?

[skyshark177]

I was reading how a pole is made and came accross an idea.
What would be the Pro's and Con's of increasing the pre-bend in making a pole?
If the Pre-bend was increased, would it help the vaulter get on bigger poles, jump higher hights and use longer poles?
It would probably be akward carring down the runway, but dropping the pole into the box may not. The end of the pole would easily drop into the box and the vaulter wouldn't have to worry too much on hitting the back of the box.
I know this might be a wierd idea, but I thought I'd find out what other people think about it and if it ever came up before.

We tried some things last year - including a normal pre-bend and then another pre-bend high - give a higher plant angle effect. Various reasons - extra time, effect on structural integrity, repeatability, consistency - all toll - we decided to look in other directions for the next generation of poles. We believe the poles available to the market today are the best ever - but we also believe if you are not pushing forward you will eventually fall behind.

PS: Currently to increase a prebend in the pole it requires reheating - poles are extremely fragile during this cycle - the bigger the pre-bend the more care and danger of damage during this process - I am sure some of the Giants of the Industry will chime in also

Becca - the time of post - is it your systems clock or the individual posters clock? When I posted - went back to look and was the only post - come back a few minutes later and another post is ahead -

with increased pre-bend in mind, we may have to change the deminsions of the box, like increasing the angle of the back of the box and allowing the standards to move back more and a long pit in the back.
I just think that to increase the world record, these are some things that would have to be increased and of course make a major change in the sport.
Hey, the event has changed in the past; pits, poles, runway, bar, box, have all been improved or increased to increase the world record.

** Just another thought **

Good call yes a curved pole does need more of an angle and a small curvature of the pole does allow the athlete to manage stiffer poles for a better return. We do see the new Flame pole tip we are developing to be a way to increase the angle in the box to allow the curved pole to have an advantage.
Being that I am one of the Giants of the Industy I agree with Decamouse
The inside joke here fans is I am the President Director and a majority Shareholder of Giant Junior Investments Corp. (Stock Symbol GJRI) formerly Essxsport Corp. a Nevada Corp. ( Stock Symbol ESXS)name changed on June 5th 2004, located in Irvine Ca. and GJRI is now the owner and parent company that owns the new Texas Corp called Essxsport Inc. located in Fort Worth
PS sorry my post beat you by 3 minutes Decamouse what you doing up so early on Sat. morning I had my coffee maybe I typed faster SMILE:D ????

Being and engineer - typing is not the main focus -so adjust date stamp to offset typing skills what is the new CEO of Giant Junior like - have not meet him!

Pre-bend is really a user preference - we get all kinds of requests - elites want consistenacy - i.e all their series with the same pre-bend - Gill checks every pole for pre-bend and actually have a fairly narrow accetpance band for pre-bends (if you have taken the plant tour you have seen this)- so that all poles have the same consistent transitions and pre-bends.

As far as other companies normal pre-bend - while we do get samples and keep abreast of the industry - how the pre-bend tracks from length to length and weight to weight is a function of the company and process.

PS: Dogs are used to me getting up a 4AM during week and think that is time to get up to go outside and then eat! Try to hit the track a little after 5 to get a workout in before work - insane - yes - but fits the family life better

The Skypoles we have had from Mesa did not have a 3" pre-bend (matter of fact Russ V. has one now). The bananas did have a big pre-bend (hench the name and sticker on them). So just like most of the pole vault world - depends on who and when it was done.

If everyone was built the same and vaulted the same it would be a much easier equation.

Sometimes you forget I worked with Sky Pole from 1972 to 1977
All World Class SKYPoles for elite were 3 1/2" prebent.
Accept Kjell Issaksons as he does not Rotate the pole in the plant and had trouble with the big curve of the pole when it kept ending upside down on him LOL.

Most standard Bananas were 2-3" out of line. Until Gill was the producer of the skypole.

To concur Yes the Elite want consistancy your test provides that, how evr most vaulter who understand the benifits of a large out of line curve want the biggest they can get.


ABOUT the NEW CEO Because you asked

Do not know how to adjust the time thing on this site
sorry you are mistaken
I did not tamper with it????

[Decamouse]

Bruce - you said you worked "with" - not "for" - is that kinda like saying we supplied (but did not necessarily build?)"I also said a skypole made in Costa Mesa - not specifically a banana model - believe Gill was carrying Skypoles in 76 - "wanted biggest they could get"! I will have to ask Jan or Ralph about that - but know what the likes of Lobinger, Povlov, Stevenson ask for and get.

Again - time and place in history - we don't throw wooden javelins any more - but it does have an important place in history

About the time thing - if I read Becca post correctly - it is the clock on your own computer that is the baseline for the time stamp - so if my time setting is off that would contribute to a difference based on true GMT - "Do not know how to adjust the time thing on this site
sorry you are mistaken I did not tamper with it????

don't recall saying you tampered with anything -

Enjoy the rest of the weekend

I worked for Sky Pole as their Midwestern sales Force They had no other sales force. And I bought from them also.

IN 1977 I sold and developed with SKYPOLE engineers my FiberSport Vaulting poles used by Billy Olson for his first 18' jump Earl Bell for his 1977 best in the World Jumps of 18'4"
ANd Wladyslaw Kozakiewicz 4 World Records and a Gold Medal win in The 1980 Moscow Games.

I might note these old poles are made very much like ESSX today with only a few material changes but basically the same design as asked for and designed by Earl Bell.
Still not sure about the your comments about the time on my clock on my computer which right now says 6:18Pm Central time?

PS I see you are the PV JUNKIE onhere now and I the PV DORK GRIN Thanks Becca LOL

Do you have a picture of this new pole tip?
I've read the threads in here, but never saw a picture of it.
