Making Second Hands Friction Tight

Sometimes you will find that the tube on the second hand becomes slightly loose, especially on watches used by railroad men, inasmuch as in the setting of watch one will advance the second hand by using a pegwood stick to bring watch to time. If this practice is used for a long period, the second hand tube will loose its friction, on the fourth pinion, and will have to be tightened. In doing this job, I insert tube in a split chuck, place in lathe and tighten just slightly and the job is usually perfect.
