  • The Dilemma of the Steinway Model B: A Innovative Strategy for Teflon Bushings

    Core Summary：This article introduces a Conservative & Minimally Invasive Restoration approach—a groundbreaking “third alternative” for addressing the notorious “Teflon Era” bushing defects in 1970s Steinway pianos. Bypassing costly and irreversible global action replacements, this method leverages modern tribology and boundary lubrication theories by implementing NSF-certified H1–H3 high-tech synthetic polymers. It dynamically mitigates seasonal dimensional stress…
