| Oyl-E-73125 -2- and tapered 1 in 6 like the old screw E-17786. We think this would increase the strength of the lock-screw and at the same time decrease the distortion of the piston pin at the ends, while leaving this distortion in the right direction to take up slack in the piston. We should appreciate Mr. Royce's opinion of this proposal. Oy. COPY Print E-20098 Sample lockscrew enclosed for Mr. Royce. | ||
