I believe this person had not tried it yet, but was considering it. I have a situation (newish Asian grand, tight bushings, loose block) where this might be the only way to get the CA where it belongs. Has anyone tried this technique, and if so, with what results? Mike, I tried this once on in the bass section of an older studio piano many, many years ago. Way too much trouble. Never have considered to do again. Keith McGavern
