I just installed a set of new let-off buttons on the 1970 Steinway D I'm working on at the school, using original screws. How the heck do you get the buttons to thread straight, so that the buttons don't "wobble" when you turn the screw? Although not all the screws were perfectly straight, I don't feel that was the main issue. I backed out the screws and held the button against the rail while turning screws, but still had a tough time getting them level. I feel like I did a terrible job on this, but had to get them on and get the piano to "play" for a piano faculty demo of sorts. Unhappy with my own work on this one. How can I do better next time? What's the secret? -- Paul Milesi, RPT Staff Piano Technician Howard University Department of Music Washington, DC
