Tom, I'd go ahead and build your NF2 when you get the time. It works great on an individual basis. I can use my recorded deflections for raw shaft and trimmed shaft to exactly duplicate a customer's broken shaft...or match any club to his set with about 1/2 cpm accuracy, aligned properly and do it in half the time required with a frequency machine and spine finder. Hopefully, we'll figure out the calibration modifications in the next month or two. I had another thought concerning the problem...would a $6.95 dial indicator be consistent in its acuracy from piece-to-piece? When I saw that metal workers were using dial indicators over $150, I had some doubts about ours...that is, their consistency from one NF2 to another. Maybe not a factor, though.
