the diameter of the cylinder at the lower end, and cut off a
piece the length of the cylinder proper, leaving the pivot projecting.
Now fill the cylinder with lathe wax, and while the wax is warm, slip on
the joint wire. You can now proceed to true up the pivot in the usual
manner, and when the wax is quite cold, proceed to turn and polish the
pivot before removing from the lathe. If the joint wire is properly
cemented on the cylinder, it is almost impossible to break it. After all
the work is done, the wax can be dissolved in alcohol. In pivoting
pinions to cylinder escape-wheels and third wheels, it is not necessary
to remove the wheels, but great care should be used in handling. In the
latter case use plenty of wax. Do all your centering by the outside of
the pinion. Perfect centering and sharp tools are requisite to good
pivoting. Do not try to rush your work, especially while drilling.
Proceed deliberately with your work and aim to restore the watch to the
condition it was in originally, and you will find staffing and pivoting
is not half as hard as some workmen would have you believe.
