      I can 'snug' it in tight holding the spindle with one hand and tightening the
      bolt by hand or with a wrench. Final tightening is wrench & pin.

      Do you have a R8 version mill? Mine is MT3 - nothing falls out just from
      loosening the nut - some inertial 'assistance' is always required to expel the
      cutting tool.
