Drilling a .355 hosel to make it a .370

Bought a G-Field GFT 22* utility the other day. Was told it was a .370 hosel opening. So i decided to buy a Matrix Ozik Altus Hybrid shaft for it. I get to the clubmakers today and apparently the GFT is only a .350. So i'm pissed, but i ask the guy what my options are. He says he can drill the hosel a tiny tiny amount to make it .370. I ask him if it will affect play or performance of the club/shaft etc. He assures me THERE WILL BE NO AFFECT in shaft or club head performance whatsoever. Just wondering how accurate you guys believe this to be. I mean i wouldn't think shaving down a hosel 3/100ths of an inch or whatever it is, would make a difference but i can't be too careful with my babies.

you can take the .370 shaft down to a .350 if you dont want to mess with the head. I have heard of a few guys doing this with no problems. But if you ask me, sell the shaft and get the correct one, it will make you feel so much better in the end.

i am in the other camp.. if you HAVE to do something.. drill the head out to fit. just do not like sanding down a graphite shaft to fit. if the guy has a drill press - no big deal.. and not to sound careless-- it will be better.

just me..

Yep, that's what the guy did. Drilled out the hosel a tiny little bit. Put in the Ozik shaft, fits perfectly. No marks, no scuffs and most importantly, no shaft shaving neccessary.

im doing something different i too am shafting my gfield 22* head problem is the speeder shaft i have is .335. my fitter suggested putting a shim to make the shaft fit snuggly. he says many people do this and it will not affect play at all. anyone try this as well?

You do this all the time but not the other way around.

learning something new everyday, if you asked me about this last week i wouldnt have thought it possible :atsg_smilie_roll:

Anything is possible but just not recommended. Then again, you can always try.

I had this done with two TRC's. Shim works great, no problems in performance. I've found the Speeder shafts to work great in utilities.

Putting a .335 shaft in a .350 hosel is never a problem if a shim is correctly used. the smaller tip shaft will play slightly differently to a .350 and can help the workability of the shaft, it may also help launch the ball a little higher. This is certainly the case if a .335 shaft is fitted to a .370 hosel hybrid and can increase launch by 4 degrees!

As for reamming the hosel to .370 or shaving a shaft down, there's only one winner! Reaming! I do this a lot for people who have tapered irons and ask for a shaft to be fitted that is only available in .370. Never had a problem at all.

my speeder has been excessively trimmed by the original owner from the looks of it. i suspect it is a fairway wood shaft trimmed to fit a hybrid head. i received the shaft at 39.25 " cpmd at around 265. will further tip trim it to 39" for my 22* hybrid. final cpms should match my GD ysh 85 hyrbid shafts on my 18/20.

hope playing characteristics are as buttery as the gd

succesfully added the shim without problems. had to tip the shaft a little. The speeder shaft and gfield head is an amazing combo. i got more from this experiment than i bargained for.
