A Regulating Rack spans one section or the entire action with great stability. Templates set to strike can be lowered all together as the profile of strike to represent letoff or hammerline. At strike, the templates can record the hammer spacing scale or act as strings to bounce hammers off of into check.
Grandwork tools and protocols allow all piano technicians to succeed at grand regulating, guiding beginning technicians and empowering experienced technicians.
