Losing the drill chuck key for your drill press?

Responding almost 2 years later, hadn't seen this til now.
Epoxying is when there aren't decent flat or ferrous surface for size of magnet on hand. Hot glue works too, maybe better due to greater thickness. Also, some magnets are mounted which interrupts sufficient attraction to be secure.

I use magnets also to keep pencils at hand, together with the chuck key. It is very easy to place a nut in the pencil body.
