Snapped shaft, under hosel..?


Recommended Posts

After buying a Callaway XR 3i, to remove my fear of long irons, I have inadvertently created both a monster (3i head, Fujikura Green shaft..) and a bug for club building. I am well aware that I'll never get a career in this BUT sorting bits for myself and my buddies will definitely appeal to me going forwards. I am a tinkerer by nature.

 

After re-shafting a friend's 718 T-MB 2i with a PX LZ 105 6.5 shaft, we thought he was sorted. X100 was too heavy for him, but the LZ being a bit lighter was a mutant. He swings arguably too fast (iirc 122-127 w/ Driver) and ultimately snapped the LZ shaft under the hosel. Assessing the shaft, it was a complete snap and there was no obvious sign of anything protruding into the shaft or any warping/bending. When taking the tip that was left in the head out, there was about 10mm of shaft exposes, so it wasn't even caused by contact with the head.

 

Now, was this potentially me building incorrectly, or my friend just being a monster?

I guess it's possible that the graphite LZ shaft had been sanded down too thin in the tip section. Did you really have to abrade it a bunch to get it to fit?

Other than that I'm guessing it's a flukey combo of him swinging really hard and a shaft that was a little weak. As a club builder we don't really do a heck of a lot more than clean everything and glue it together. There's not a lot to get wrong.

Was there epoxy inside the shaft?  Too much epoxy that goes up inside the shaft can also lead to breakage.

Cheers for the feedback both. It was a steel shaft, but only light sanding from what I can gather. Where it snapped there wasn't much in the way of abrasion; I'd just run a little wet and dry around the tip after cleaning then dipped in acetone before committing to the reshaft.

 

As for epoxy, I'd made certain to be slightly sparing with it so I believe there was roughly 1/4" or so in the tip.

 

I'll blame my mate for being a mutant!

I would say if you had the correct sized steel shaft and tip(tapered or parallel) selected for that iron head I would say you just had a bad shaft unless your friend grossly mishit the ball.
