On a rebuild for a small but good quality grand I am replacing all of the action parts and having some doubts about the action configuration because as I regulate samples the drop screw has to be lowered almost as far as they will go. Another relationship that appears to be off is the jack to hammershank relationship which is not perpendicular but rather it is more toward the B- side (Bob Hoff terminology). The new (Renner) wippen with the closest match to the old wippen is the one with the added heel. The old jack tender/toe seemed to interface better with the tilted let off rail than the new wippen does. The new one gives a harder feeling ledge before let off. I don't like the way that feels. I realize that more information may be necessary and I can supply it if asked. One other thing I will add is that I had to lower the plate/string plane to get some downbearing. I am adjusting the hammer bore because of this. So to restate my question: What is indicated about action geometry when drop screws must be lowered so far in order to attain suitable drop? I would appreciate your comments. Bob Hull __________________________________ Do you Yahoo!? Yahoo! Small Business - Try our new resources site! http://smallbusiness.yahoo.com/resources/
