It Finally Died... Sort of :P
The time has finally come and the handle has given up on my N90... It happened while I was warming with some clears. Everything felt normal until about a few hits in when I noticed that the last hit had not only gone way wide and out, but also felt spongy.
I immediately looked at my racket only to notice that the handle was twisted and looked like it had been pulled out a few mm's.

When I got home, I proceeded to disassemble/unwrap the grip. This revealed a loose cone and underneath it, the wood had cracked and split.
Attachment 136763Attachment 136764
After I separated the racket from the racket by pulling it out. But before I even started to pull, the screw fell out from its hole... I immediately now that the screw had broken. As I was pulling it out there was an abnormal amount resistance.
I separated the two parts and looked at the shaft only to see that now I have to deal with this.......................... :
Any suggestions on how I can get it out? And no, there is NO way I'm going to drill it!
How ever i was thinking maybe I can take a small punch and "punch" in a hole or multiple holes to make a slit and take a really small flat head to try and screw it out?
I know I can just glue it back together without the screw but I won't be as confident about its durability if do : P

any sign that there were glue on the shaft?
Yonex rackets have glue there. i would be very surprised if LN rackets relies solely on the screw for structural integrity.

@wlachan, that tool seems like its only effective if the screw head is still attached which mine has broken off...
@kwun, there was glue but it was in the shaft's cavity

Maybe you can leave it there and drill another hole higher up for a new screw? I must say the shaft looks remarkably free of glue. Perhaps that's the reason the screw would break off like this.

I would, but Im not too fond about the idea of putting a drill to it S:
I agree and there was also a great deal of dark dust that was all over the shaft when i took it out. maybe the pre-glue preparation wasnt done so well or even at all?

It's hard to tell w/o seeing the actual item but checking the wood might give you an idea. To reglue it, I would clean off the shaft with lacquer thinner first (don't use alcohol), then apply slow cure epoxy (less brittle ones would be better) on both the wood and the shaft before putting together. Apply more and squeeze it out. Do the same to the plastic cone but better to roughen the inside with 320 sand paper first. As to drilling, I would hand drill it carefully all the way through and use a longer screw. Squeezed out epoxy can be cleaned off nicely with alcohol so long as it's not cured. Set it aside for a week before playing.

There's no need to use a screw at all - Gorilla Glue is strong enough on its own. It's what I use when changing handles.

use a sewing needle to tap it out? maybe something from a fabric store thats more blunt...
jeweler's hammer is lighter...

If you want to remove the screw, you're going to have to drill it out, don't push it out! You could break the carbon.
If you are to drill it out, you need to use a highspeed hardened drill bit as the drill bit can catch some of the carbon fibre and tear it if at slow speed. Best to use high speed but low force.
However if you don't want to use a retaining screw, and simply rely on the glue to hold it in place, you will need to give the glue/resin a good keying surface to bind to. To do this, use some coarse sand paper and rub the carbon to roughen the surface then clean off the dust before using the glue/resin.

Im fairly convinced that there is/was glue used to bond the shaft and handle together because the cavity of the shaft is filled with some hard yellow stuff.
Gorilla glue has been out of the question to start with.
No, I am NOT going to tap it out but I have found something much stronger than a sowing need that i can use to punch holes in the broken screw. It's sort of like a pick used for sowing to pull out/loosen stitches in clothing.
I'm still not too fond about the drilling though.....

Is the screw loose? If so, there is another trick you can try. Apply some quick drying glue on a toothpick and set it on the broken screw, then unscrew it once cured. If that doesn't work, just drill the damn thing.

The screw is a little loose on one side to the point where I am able slightly wiggle it around. I've thought of your idea earlier but didn't give it a try because I thought it wouldn't work for some reason...

There are screw remover tools you can buy, I have a few sets which work really well. They basically look like a drill bit but have a reverse cutting head. So as you turn the tool, it digs into the screw head to allow you to turn it out. I would try that first if you can borrow one from somebody.
