Can you spot a shaft extension?

[dokex]

Here is the deal: two identical drivers, down to the shaft and grip. One of them is cut to length, the other has a properly installed one inch extension. Do you think you could tell which had the extension, simply by playing the clubs? BTW, swing weight is identical.

[noodle3872]

No

[kwcsports]

nope

[lefthack]

Not if installed correctly.

I'm just waiting....

I've got one inch extensions in half my irons, and can't tell the difference.

The one with the extension will have a higher total weight.

 

Depending on the extension used it could be as much as 10g heavier due to the extra headweight needed to counteract the extra weight in the butt due to the extension. That would be noticeable in play by a lot of people.

Given that scenario swing weight won't be identical. There would have to be another alteration to make it so.

As described....absolutely no difference in performance in those shafts!

Added weight to the butt end is meaningless.

Buy the one that is the cheapest....non-issue.

OK, let's change the scenario. You have one driver head, with two shafts with adapters. The first shaft is cut to the proper length, and the second is extended one inch. The driver head weight will remain constant.

If the second shaft is 1" longer than the first then the swingweight will be about 5 - 6 SW heavier.  If they are both the same length...no SW change.

Changes in weight in the butt end have no affect on the SW of a club...ie like a midsize grip vs standard grip.  The SW is dictated by lever length and weight at the end of the lever, ie head weight.  Pivot weight, ie grip end is meaningless to that calc.

I assume you mean extended to be the same length.

 

In that scenario the extended club will have a slightly heavier total weight and a slightly lower swingweight. Again, how much will depend on the extension used. The two clubs should feel the same stiffness wise assuming the tips were trimmed the same.

 

Some people will notice it, most won't.

Yes, extended to the same length as the shaft w/o the extension.

BirdieBob gets it.

In your first question were they both the same length? I think everyone was assuming they were. Which would be the same as your second scenario?

Yes and yes.

Sort of. 

 

Measured SW will be different. Total weight will be different. Whether that matters or not will depend on the golfer.

I bought a Hogan  h2 Hybrid off eBay had a 90 g butt weight in it.

Knew it as soon as I picked up the club

I wasn't talking about counterweights, I was referring to lightweight plastic extensions, LOL.

[GLF4EVR]

Did close to a 2" extension for a neighbor years back.  Had to use just a little lead tape on the extension to get the SW where he wanted it.

 

Would back up @lefthack statement.....not if done correctly.

 

Last winter I did my set using Tuttleman's MOI equation.  Some shafts already had extensions in them.  I converted from 1/2" increments to 3/8".  Used shaft lengths without the extensions to calculate what the actual shaft weight would be at the desired shaft length so the extensions would not throw off the desired MOI numbers.

If they are both the same length, I doubt I could tell a difference.
