Shop tools for precise piano regulation across both upright and grand actions, supporting the full sequence of tasks: key leveling and dip, aftertouch, hammer blow, let-off, drop, repetition, damper timing, and sharp height. Offerings include key easing pliers to correct bushing friction, wire-bending pliers for spring and wire shaping, sharp-leveling devices, compact and multi-function regulating gauges for consistent measurements, tautline and spacing tools, grand key leveling leads for balancing and leveling keys, multi-position regulating racks for efficient access, long-reach and offset screwdrivers for slotted and spade-head regulating screws, and service aids such as damper screw regulators and guide-rail bushing easers. Together, these tools provide the measurement, leverage, and reach needed from initial keyframe preparation through fine regulation of hammers and dampers.
