Flat hammers can be very dangerous for a piano, and sound less than satisfying. Here is a side by side comparison on a nice little studio we serviced for @trimblehousenash -Nashville artists retreat studio. They acquired a one-family-owner 1931 Bradbury studio piano that needed a little maintenance, but was otherwise in excellent condition. Flat hammers are the result of excessive or years-long play without proper maintenance. The sound of the piano is no longer crisp and light, but rather duddy and lifeless. The deep grooving of the hammer felt caused by the strings can eventually deteriorate and break apart, remedied then only by replacing the full set of hammers. To prevent that costly job, hammers should be filed down and rounded back out. These hammers now have quite a few years left on them. #amopianos #trimblehouse #trimblehousenashville #beforeandafter #hammershaping #pianohammers #flathammers #partsofapiano #pianomaintenance #maintenance #filing #piano #nashville #nashvilletn #wood #metal #felt #antiquepiano #1931 #vintagepiano #antique #vintage #hammers #picoftheday
