Tool post modification allows easy turret lathe cutting-tool alignment [PDF]
, 1966 Modified tool holder and tool post permit alignment of turret lathe cutting tools on the center of the spindle. The tool is aligned with the spindle by the holder which is kept in position by a hydraulic lock in feature of the tool post. The tool post is

A three-step MTOC fragmentation mechanism facilitates bipolar spindle assembly in mouse oocytes
Nature Communications, 2015 Assembly of a bipolar microtubule spindle is essential for accurate chromosome segregation. In somatic cells, spindle bipolarity is determined by the presence of exactly two centrosomes. Remarkably, mammalian oocytes do not contain canonical centrosomes.

Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]
, 2019 The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...

Thirty years of search and capture: The complex simplicity of mitotic spindle assembly
Journal of Cell Biology, 2015 Cell division is enacted by a microtubule-based, self-assembling macromolecular machine known as the mitotic spindle. In 1986, Kirschner and Mitchison proposed that by undergoing dynamic cycles of growth and disassembly, microtubules search for ...
