Control stick mixer adjustment

Spent more time fine-tuning the mixer by adding various washers between the halves of the bushings.  Removed the mixer completely so that each bearing point could be worked on independently, which made it easier to tell which part was either too loose or was still binding.  Adding washers that have a slight wedge shape frees the mechanism and enables it to move freely, but it moved much too easily and had too much wobble, so more adjustment is needed.   Hours: 3
