I have never (I'm ashamed to admit) used this technique. But, yes it would take a few minutes to cut the punchings, but it will also save you from removing the stack. Further, it will provide the consistency of the actual action providing the weight on the back of the key - potentially resulting in a more accurate key leveling. Am I right with these statements? Do you have some technique to put an uncut punching on a grand center rail pin without removing the stack? Terry Farrell   </BLOCKQUOTE> Terry Leveling keys with the stack on is a good way of doing it. I am not sure it is a more accurate way or not. I use weights hung on the back checks to level keys. Although I do this on the bench, I have done it in the piano. I don't see how you can put a punching on a center pin without removing the key, unless you cut a V in the punching. As I said, I have done this in an emergency. But when I have tried doing it for a complete leveling job, I found that I bent, broke, pushed out and disturbed the other punchings too much, causing more work in the long run. Leveling keys is not an easy, quick job. The more time you take doing this part right, the easier it will be to get the action regulated Wim </HTML>
