Spindle disk diameter

Latex stability. Effect of stirring speed and spindle disk diameter. Figures 10. and 11. show how sensitive the stability test is with regard to the speed of stirring and the diameter of spindle disk.

Careful examination of Fig. 3 reveals that the disk and its spindle connector would need to be made in two parts to enable the assembly of this prototype. A slightly larger access where the bonnet connects would enable a composite disk and spindle to be inserted from above. However, the spindle needs to be able to pivot within the disk mounting to enable the three-dimensional fluid forces to tilt the disk without causing excessive friction in the spindle-lift guides. Nevertheless, assembly would be simpler where the disk is inserted from above, and any reduction in diameter (and hence material) confined to the spring chamber. 

Flaring Cup. An abrasive wheel shaped like a cup but with a larger diameter at the outer (open) edge than at the bottom of the cup, the bottom being the disk that fits on the spindle.
