Never lose your drill press chuck key again with this handy tip.
Self-Winding Leash for Wandering Chuck Keys

I got tired of hunting for my drill press's chuck key, so I gave it a permanent home. I drilled a 58 " hole near the top of the column. Next, I slipped a dozen or so 14 " nuts over a 24" length of sash chain, using a cotter pin as a stop for the nuts. Finally, I attached the other end of the chain to the chuck key with a key ring, and then dropped the chain and nuts into the hole.
