The spindles are attached to the viscometer by screwing them onto the coupling nut on the lower shaft
(see Figure II-3). Note that the spindles have a left-hand thread. The lower shaft should be secured
and slightly lifted with one hand while screwing the spindle to the left. The face of the spindle nut
and the matching surface on the lower shaft should be smooth and clean to prevent eccentric rotation
of the spindle. Spindles can be identified by the number on the side of the spindle coupling nut.
