Swingweight for lightweight shafts

[DanKel]

I need help. I'm fairly new to clubmaking, but I've reshafted a couple sets of irons without damage or loss of limb.

 

Age has caught up with me, and the Mizuno shaft selector recommended the Nippon NS Pro 950 Ultralight shafts in sitff. Got them. Took the DGS300 shafts out of my Mizuno MP-37s, and started to put the new shafts in. So...here's the question...does it make sense that I need to put more weight in the tip end of the shafts than what was in the old shafts? I'm no genius, but I thought that the lightweight shafts would require less tip weight to get the same swingweight.

 

What am I missing?

 

Thanks for any help offered.

You will need more weight in the tip with the lighter shafts to get your swingweight where it was with the DG.

I think it works on the swingweight scale having a 14 inch fulcrum. It means on a 37 inch shaft there is 23 inches overhang that is lighter hence the need to add weight.

DAN:

REXROH is absolutely right. As shaft weight drops, the amount of headweight required to achieve the same swingweight has to increase.

But do keep this in mind too. Even if the golfer has been losing clubhead speed and that is the reason for the move into the lighter shaft, if that golfer still has a short backswing + forceful transition move to start the downswing + a faster than normal tempo, they may need a little higher swingweight with the lighter weight shaft.

BUt if the golfer is not above average for the forcefulness of their transition move or their tempo, then using the same swingweight for the lighter shaft that they had with the heavier shaft is a viable starting point in the switchover of the shafts.

Thanks for the responses. Clubs were reassembled at D0. I was limited to adding 10 grams in the lightest club, then made the others match. Lucky for me, leisurely swing with a slight pause at the top works great! Harmony (in the form of height and distance) in the universe has been restored. Thanks again.

I find that a d2/3 swing weight can feel good in a stiff, but can make the head of a regular feel much heavier and much more lagging in the swing.

D0 sounds like a great weight with a leisurely swing. Enjoy the new shafts.
