Determining hammer head angle in upright piano
« on: June 15, 2020, 08:48:08 AM »
Gday folks, I want to know how one might measure for the angle of a bass hammer head in an upright piano in order to drill the replacement. The bottom three heads (nos 1,2&3) are missing. How does one determine the angle for boring/drilling a replacement hammer head?
