drill chuck key chuck

thingiverse

I had to get a new key for a rusty old drill chuck, however the one I got from the shop did not fit, as the peg diameter was slightly too large. I figured that I could just grind the peg to size with a rasp/file by turning the key in another drill, but I could not fit the key in the drill chuck due to the key handles being crimped in place. I decided to make a fitting to mount the key in a drill. Slide one half onto each handle of the key and use a zip tie to hold in place, then insert into the drill chuck. I have no idea if anyone else might find this useful, but I just wanted to illustrate an idea I was able to quickly implement and solve a problem I had. I guess this could be a starting point for a drill lathe or wire twister? Also as a bonus this "chuck" could also be used to "drive" the key in another drill chuck when you're too lazy to turn it yourself ? :P I designed this model in Wings3d and printed the file in PLA using low quality settings with support. The finish is rough but the part was effective. EDIT: Just a few quick thoughts on safety: obviously drill chucks & keys were never meant to be used like this - If you ever have any reason to spin up a drill with parts like this on the end, **BE CAREFUL!** Wear eye protection and watch out for the spinning key handles. I didn't have any issues with my part, but if the part is broken or poorly mounted in the drill, of course there is a hazard of parts being thrown from the end of the drill!
