Torque of Finished Clubs

NOTE 12: Several clubmakers have asked if my CS II or III could measure the torque if a finished club. I fooled around with this some time ago and it is possible (and at times very revealing!). The obvious problem is the club will not fit through the hole in my bearing bracket. I built a split bearing bracket to overcome the problem. (If you'd like one they're $35). At first I wondered if the moment of inertia of the club head would affect the results. My assumption was that it wouldn't and I was right. Moment of inertia, which determines torsional frequency, is mass time length squared. The mass of the head is fairly high, 200 grams or more, but the length is very short compared to Club Scout's torsion bar length. Whereas the head had absolutely no effect the grip did. If the grip is left in place it will increase the torque about one degree. A finished club measuring six degrees therefore actually has a five degree shaft. I ran a couple of tests to see the variation with different grips.
