They seem to be particularly susceptible to this problem.<o:p></o:p> <o:p> </o:p> If you are having trouble following = <st1:PersonName>Paul</st1:PersonName>’s description, the dags are 4 blocks of wood = in the back of the action cavity screwed down to the keybed. They act as stops when pushing the action in. They also have a slot that = the back of the key frame slides into which holds the back of the action = down when the piano is tipped up. Usually the dag on = the extreme bass end and the one on the extreme treble end has a brass screw screwed into that slot. The factory uses these screws as temporary stop adjusters for setting the strike point. This enables them to slide the = action in and out for regulation without having to use the cheek blocks to = properly locate the strike point. <o:p></o:p> <o:p> </o:p> This is the sole function of these = screws. In the field we use the cheek blocks for setting the strike point. The = problem you are encountering is that the sliding line established by those stop = screws is not parallel to the sliding line established by the cheek blocks. = This causes the action to bind against those stop screws when attempting = una corda. = <o:p></o:p> <o:p> </o:p> The remedy is simple: turn the = screws in a full turn. You could also back them all the way out and throw them away. = But leaving them and turning them in a turn does give you a roughly accurate strike = point without the cheek blocks. After making this simple adjustment the cheek blocks = alone will determine both the strike point and the sliding line of una corda shift, = precisely what you want. <o:p></o:p> <o:p> </o:p> It wouldn’t be growing action brackets.
