Regulating Capstan Screws

Regulating capstan screws is also known as adjusting lost motion. Lost motion is the amount of movement a piano key has before the note is started. This movement is known as lost motion, and this is unwanted. Too much-lost motion causes the piano to not receive a full blow from the key. If there isn't enough lost motion the hammer won't sit back on the hammer rest rail. Regulating the capstan screws will fix these problems and the keys will play smoother with less slop. Regulating Capstan Screws is a service that is needed on most pianos and will heavily improve the playing quality of your piano. Regulating Capstan Screws Cost: $150 for upright and grand pianos.
