I doubt I have the answer but consider the identifiable factors; Head weight Shaft Weight Shaft length Spine location Grip weight - plus tape and/or adhesive to install.
We all know that SW changes approx 3 points per 1/2 inch lenght. We know that one SW point equals about 2 grams. We know that SW, even though "perfect" on an ungripped club, will change significantly when the grip is installed. Given all this, I have yet to build a set of irons with matched SW, freq, length and overall weight. I'd be surprised If anyone has. I've weight sorted shafts and grips, spined them. Sorted grips for weight. I've even weighed the tape used to install the grips. I've set head weights 7 grams apart. I still get a variance of a point or so when the final work is done. Here's another oddity . . . If you bend the lie angle either up or down say, 3 degrees, you'll get a small difference in SW because the toe sticks out further from or closer to the SW scale. Infinitesimal, but it's there. So I'd say the final place to adjust SW isn't at the head. But working at the butt end . . . the grip, will allow for some small changes in ending SW. Formula? I guess you'd have to ask Dr. T or one of the guys with more smarts than I have ;D TFlan > --- Bob Barrette <[EMAIL PROTECTED]> wrote: > > > Hi All: > > I dry fit all my clubs to my desired frequency, my > > problem is, getting a uniform swing weight > > throughout the set.
