On slow playing I see no purpose in the checks. All would be accomplished if they did not exist.<br />On repetition the it seems to me that the jack should be released to just below the nose of the abstract so as to enable the abstract and hammers to be projected upwards for the second blow.<br />It seems to me that if the jack is not below the nose of the abstract when the hammers are in check the repetition will be propelled only under the force of the repeat or abstract spring.<br />Any enlightenment on this matter and the interaction of these two parts of the action would be appreciated.Vladohttps://www.blogger.com/profile/14854833248082250963noreply@blogger.com
