shaft problem

[kovalchuk71 212]

my int synthesis isnt really accepting int blades anymore. it seems the shaft is too big? is this because of wear/warping or is there something wrong? theres not much if any glue on it, but it never really needed it. is the shaft ruined or should i try a sr. synthesis or should i put a bunch of glue on it

Sounds like it was overheated and bent out of shape.

[kovalchuk71 212]

could it be from constant heating up? is there anyway to fix it?

[Chadd 916]

It's more likely from getting too hot than just heating it up frequently. I've had shafts that I changed blades close to a hundred times without any problem. Once it's bent out of shape there's no way to fix it.

Not maybe from heating over and over again but more likely it was overheated at some point or possibly a blade was put in that was a little too big and it stretched the hosel opening. Try using a piece of tape around the tenon and putting more glue on the blade.

how do u know when it is too hot? i dont even heat it much at all. maybe 2-3 seconds while waving the gun on each side of the shaft

i heard a couple of players complain about this. they said by heating the shaft over time has balloned up the size.

not really much you can do except keep on adding tape over the tenon on your blade before inserting into the shaft. adding more glue is not going to help at all.

What temperature are you using now? I use 500f with a heat gun for about 5 seconds on the shaft. It's been working so far.

[kovalchuk71 212]

i use the high on the heat gun. but i barely put it on each side. like 2 sec on each side of shaft

I think if your heat gun is able to soften the glue sufficiently in only 2 seconds, it is way too hot.

That being said, I think a lot of people have a tendency to over heat the shaft, or heat the shaft up too fast. I hold the heat gun about 3/4 of a foot away and rotate the shaft so I don't heat the crap out of one side before the other. I try tugging on the blade every half minute or so until i can feel the blade coming out. Heating it up until glue bubbles out, which I know some people do, is not necessary. The name of the game is gentle heating giving time for the heat to conduct through the shaft to the glue. Like roasting a pig. Hope you have better luck with ur other shafts.

[kovalchuk71 212]

i just wait until the shaft feels pretty warm, i dont think about the glue.

[Chadd 916]

No wonder you have problems

[chippa13 1844]

I just heat with the heat gun on high while rotating the shaft and moving the heat gun back and forth over the tenon area. As soon as I see the glue bubble I know the blade can come out. I've changed blades on shafts more times than I can count and I haven't had any problems like he's having.

If he only heats the shaft for like 2 seconds on each side then he must be forcing the blade in because the shaft will expand slightly when heated which allows blades to be inserted and removed. By forcing the blade into the shaft it stretches the opening.

My sr. Synthesis had always been a little on loose side when taking blades since the first day I had it. It usually takes me a few minutes to evenly heat the shaft before adding/removing blades, so I don't believe I've overheated the shaft since it's the same fit as it was new...

So has anyone else found their Synthesis shafts to fit a little loose as well? I'm using Synth. composite blades btw.

[chippa13 1844]

I have always had to use a piece of tape around the tenon of Synth blades with Synth shafts. That is a common thing.

Thanks, chippa. I'm doing the tape on the tenon as well. I believe the idea of the grey Synth. glue is to expand when cooled so it fills any gaps between tenon and shaft. I don't find it works very well though.

That stuff actually works decent if you put some inside the shaft before inserting the blade.

It must have been the -20C weather I was playing in during the past winter that possibly cracked or shrunk the glue a bit.

[chippa13 1844]

The real problem with that stuff is that when you slide the blade in there isn't enough of it that stays on the tenon and that is why it doesn't hold well. Putting some inside the shaft before sliding the blade in helps.

I'll give that a try next time since I've got alot of the grey glue left over. I think it doesn't work well for most people is because the glue gets thin and runny when heated so it's a mess to work with.

[kovalchuk71 212]

that may be it guys. u guys have problems with the size of the synthesis tennon too? i started using tape a couple days ago on the tennon and it is a way tighter fit. maybe its just a common problem with all the shafts or blades. or maybe its the glue. i dont have much or any at all on my blade so myabe thats it

[kovalchuk71 212]

so maybe it was something w/Easton?

My hair dryer seems to be quite powerful in terms of heat and it only took around 2 mins of rotating the shaft and heating it along with the blade in order for it to be hot enough.

I've used the same blade in an Inno tapered shaft and it fit very well with no tape added. I'm fairly certain it's the Synth shaft and not the blade tenon that's big. I suspect this may be by design, relying on the grey glue for padding.

[kovalchuk71 212]

so i need the gray glue? where can i get it?
