Unusual Screw-On TT Steel Shaft

[rogjack6112]

I found a RBZ 7 iron with a threaded neck and a screw over collared shaft.?? I can't find any similar design. I will try to post photos. Thanks for the help. Roger

It looks like it’s from an early fitting cart or kit.

Correct. Here is a Titleist version.

Thanks I suspected it was a shaft exchange testing mechanism. Exactly what is a fitting cart. Thanks for the reply. Roger

Most driver shafts are interchangeable. I have six or seven that fit my driver.  Sometimes I just swap out shafts for various reasons... always tweaking.  Why doesn't an OEM do this for an entire set of irons?

Geez... is everybody out Christmas shopping???  'Cause most of you sure aren't on the course.

There's a difference between swapping out a driver shaft and swapping out an entire set of iron shafts. How many people would want to do it? The cost to manufacture something noone wants would be insane. That's what the fitting irons are for -  so you don't have to do that. As an example, buying a driver for a good price on ebay with the wrong shaft, selling the old one and buying a new shaft makes sense financially. Not with a whole set of irons.

Why would they? Who would want this besides apparently, you? 😃

If you’re going to spend the money to buy a bunch of different shafts and swap them out for whatever reason, why wouldn’t you just get fit properly for the right head and shaft combination in the first place?

My bad.  I should have clarified.  You would borrow, rent or buy several shafts for your 7 or 6 iron two/three years after your fitting, when your swing or age has changed.  Then you could find a shaft that works for your irons at that time.  And then dump some money on a full set of shafts... to go with your favorite iron heads that you don't want to give up.

Clarifying the clarification.

Among the reasons why that would be stupid, includes the extra weight they'd have to put in the heel/hosel/ferrule (and the lack of any kind of ferrules) which would compromise the design of the clubhead.

Erik, I always appreciate being called stupid.  It's the Christmas season, you could be kinder.

So when you get a fitting... are those clubs in which they change the shaft heavier in the heel/hosel/ferrule?  Then what good is that kind of fitting if your ordered clubs are going to be lighter?  I did a fitting a couple weeks ago and I assumed the weight of the club was the same (as the ones I would buy), even with interchangeable shafts.

I didn't call you stupid, I called the idea ("that") stupid.

Generally, yep.

Some make some small adjustments for the fitting club because they don't have to last several years to balance them out a bit. Some don't do much except add the adapter sleeve. Some fitters will keep the swing weight the same but the static weight will be a bit higher.

But often, simply, what you are fit with isn't what you end up playing exactly. Same shaft(s), same length, same lofts, same lie angles, but the swing weight might be off slightly, or the static weight… etc.
