View attachment 66997Hi,
I did the "zinger" bit for several years. I just plain got tired of the thing pulling on the chuck key all of the time. So I "cut the cord" so to speak. I put an earth magnet in the center of the lever used to lower the bit. Pics, taken just for you, attached. You will notice significant wear on the earth magnet---it has been used a lot.
When I was young, having a drill press in a home shop was about as common as having a Rolls Royce sitting in the driveway. I don't know about other places, however in Ontario, Calif., if you had three electric motors on your property you had to go and get a commercial license. If you were reasonably affluent and lucky you might have an electric motor on your washing machine. Several years later electric refrigerators started showing up in private homes (that is electric motor number two). So the politicians figured if you had electric motor number 3, you were running a business from your home. So you had to get, and pay for, a city license.
Anyway, all that history was just leading up to the fact that I was taught, at the early age of 5, YOU DO NOT LEAVE A CHUCK KEY IN THE CHUCK. That was taught right along with, you do not run out into the street, you look both ways before you cross the street, even though it is a divided street. Aside: Ontario had the world's longest divided street. It was 200 feet wide, with lawn and two rows of pepper trees planted for its entire length (are you ready for this) of seven (yep 7) miles. We were always having people who had never seen a divided road tooling along on the wrong side of the divider. I have already given you one "Old Man" story so I won't tell you why I remember that Euclid Ave. was 200 feet wide.
Gad, old men do ramble don't they!?!?
Enjoy,

ps. I also cut off the spring loaded prong that ejected the key in case I was the forgetful type.
I too had problems with barked up knuckles from the spring pushing the key out just a wee bit; then when I put on pressure, the key would slip out of the gear and vola, blood.
