Strikes me as a very typical hammer replacement job done by someone not fully aware of touchweight concerns. God knows I've been guilty of this kind of thing too in earlier years. Typically, this kind of thing results from a relatively inexperienced tech who has read or heard some routine for doing the actual physicalr replacement of hammers, and thinks thats all there is too it. Often you can look at the job and see pretty good hammer allignment, nice tail lines and strikeline... attention paid to good and consitant rake. This is also typical of young techs doing this job... they want it to be good. If you will take a few strike weight (SW) samples, (5 or 6 will probably do) I expect you will find that the new hammers are around 1 - 1.2 grams on average heavier then the old ones. In which case you will need to remove that much SW. If you are not familiar with Stanwood routines... this is a great opportunity to get started. But all the hammers on the appropriate SW curve (that most closely matched the origional set) and your customer will be very happy indeed. Cheers RicB
