>Susan, >Four days ago I just finished easing a whole set of tight hammer shank >flanges in a Steinway Grand by applying "Protek" with a syringe. At first, >I thought it worked wonderful. Two days later, however, the same centers >were tighter than before... >Hans Sander, RPT In order for Protek to be effective in these situations, you have to get physical with the flanges as well. By removing each wippen /hammer assembly and working them to death [back & forth & sideways] will free the verdigris resistance. There might be some follow-up work, but not much for an actively played piano. Keith McGavern Registered Piano Technician Oklahoma Chapter 731 Piano Technicians Guild USA
