Hello all, Gluing test hammers onto the shank is my preferred method to determine the optimum strike point. I prefer to fit test hammers slightly further out on the shank (2-3 mm) than the original hammer line (you may need to use new shanks for the purpose of fitting test hammers if you are planning to retain the original shanks). This allows you to test strike points further out than standard, without having to remove the dags. It is usual to test the first and last and two intermediate hammers for each of the top two treble sections. The action and key-frame assembly is moved in and out from the standard position, as normally determined by the touch block guides, until the required strike adjustment for each test hammer has been determined and recorded. The adjacent new hammers are then glued on their shanks at the adjusted strike length. Pencil lines are previously drawn onto the strike points of all test hammers and their adjacent hammers to facilitate accurate placement of the adjusted hammer position. The test hammers are not removed until all adjacent corrected hammers have been fitted.
