Piano Action Parts

Find the components needed to restore and regulate the moving mechanism of grand, upright, and spinet pianos, including jacks with flanges, universal and model-specific whippens, hammer butts with associated springs and cords, damper levers and top damper flanges, backcheck wires, vertical damper spoons, trap lever springs, and clip-on bridle straps for proper key return. Supporting hardware such as center pins, tapered round key leads for key balance, nylon pedal brackets, let-off regulating screws with spade heads, and spinet lifter grommets addresses common wear points and fine adjustments. Options include brand-specific patterns (e.g., Steinway, Kawai) alongside universal fits, with items available individually or in multi-piece sets for single-note fixes or broader action service. For best results, match selections to action type (grand vs. vertical) and verify critical dimensions—pin diameter, wire gauge, screw thread, flange style, and part geometry—to ensure proper fit, reliable repetition, and consistent damping. This collection is organized for technicians and experienced DIY caretakers performing repair, regulation, and maintenance tasks.
