A video disc signal pickup cartridge is described wherein the stylus arm is coupled to the cartridge body by a highly compliant relatively long, flat member suspended vertically from the top wall of the cartridge. The stylus arm is coupled to the member by passing one end of the arm through a tight fitting hole in the distal end of the member. The member is necked down near the hole to increase torsional compliance with respect to axial rotation of the stylus arm. The proximate end of the member has an expanded compliant region which is compressed for passage through a mounting hole in the cartridge body and allowed to re-expand to compressively retain the member in the hole.

A technique for positioning a stone utilizes a pencil comprising a shaft having at one end a handle and at the opposite end supporting means adapted to hold a stone upon the application of a closing force thereto. The shaft has apparatus for adjusting the length thereof, and a housing fitted over the shaft between the ends thereof in a manner allowing the shaft to be frictionally rotated therein. The housing has apparatus for applying the closing force, disposed at one end thereof adjacent the supporting means, and is adapted to provide the closing force when the shaft is moved longitudinally along the housing.
