Then you have forgetting the chuck key in the chuck (duck!)


I have a serious suggestion to solve that problem. I am a shop (carpentry)
teacher, and it is convenient, impossible to loose a key, and safe.

Tape (or buy a holder) the chuck key to the power cord, about a foot from
the plug.

You have to unplug the drill while changing bits. (good idea)
You keep from misplacing the chuck key (a good thing)
You never will turn on the drill press with the chuck key in the drill. (a
very good thing)


My drill press has a foot momentary contact switch on it. When I was
cutting out the lightening holes in the wing ribs for my RV-6 I clamped
the rib to the press table in two places before ever spinning the fly
cutter. I figured the two clamps plus the foot switch would lessen the
chances of doing open chest surgery on myself with a spinning wing rib.

The chuck key for my lathe has a spring on it. You have to press the
key into the chuck and, as soon as you stop pushing on the key, the key
pops out of the chuck.

The drill press we had at work had a safety interlock that really
worked. You had to put the chuck key arm in a switch before the drill
press could be turned on. The chuck key arm would activate a momentary
contact switch in the circuit for the drill press... no chuck key in the
switch, no drill press operation...
