Anyone have a Callaway left hand X-Forged 6 or 7 iron head I can build up as a demo club to compare to a Mizuno MP-30 which my oldest son plays. He has a + handicap and would like to compare this Callaway head to what he games today. I found single heads on eBay but just RH'ed . thanks Harry

Ok here is what I did exactly. Not really concerned with tip weighting because I used actual heads 3 -PW mesured at actual lengths. Using one shaft per frequency slope ie...  Rifle chart 4.0, 4.5, 5.0, 5.5, 6.0. 6.5. First dry fitted a 3 iron to the slope frequency for  a rifle 4.0 at 39 inc

Actually when I first came to work at KZG I did tipping profiles for a complete iron set at diferent stiffnesses with both a 2.5" clamp and a 5" clamp.  What I found is that at the hgher frequencies and shorter clubs like 9, PW, and wedges was that with a 2.5" clamp I got a straight line slope.

TFlan you are indeed correct, it's important to also state the tip weight used. For irons and woods I use a 205 gram drill chuck. What do you use for wood shafts, do you still use 254 grams or do you drop it down to 205 gram wt.? I wonder what the difference in cpm would be using a GS 5" butt

How come you don't mention tip weight? That is certainly a major factor in determining freqs regardless of clamp insertion depth. Freq'ing with grip on only shows fewer cpm's and has nothing to do with the flex of the shaft, It's simply a matter of choice, as long as the choice is consistent,

Bob, I think the point that Harry was making regarding the Braly shafts is, why not redraw the frequency charts based on 5" clamping? (generally considered to be the clubmaker's standard). His physical designs can be measured a million different ways (clamp length, tip weight, gripped/un

The frequency measurement instructions/methods on the original Brunswick shafts were very precise, and to my understanding factory measurements were always done with a 2.5" clamp on ungripped shafts and at a specific clamping pressure. The commercially available Brunswick machine that used to be s

Hi Harry Why not a 5" inch clamp.  The BTR shaft is designed by the same guy that designed the rifle shafts. It is basically his next generation of rifle shaft but improved in the fact that with the new machinery he has now he doesn't need to reinforce the tip, so the BTR doesn't swing weight q

Robert, My 48-inch driver in cart bag just barely fits across the back of my '04 Quest minivan. A friend's STS Caddie trunk is OK, too. Won't fit across the trunk of wife's '06 Max and a lot of other vehicles unless driver is out of the bag and angled. Good luck. :-) Bernie [EMAIL PROTECTED]
