Not wishing to appear pedantic but I had it hammered into me at an early age in Davy & United's apprentice training school that you NEVER, ever, leave the chuck key in the lathe chuck. Same would apply to the crank handle in the other end, it ought to be spring loaded so it drops out of mesh when not in use, even though the power might be off and the drive de-clutched. You just never know.
