Like this use of an seemingly old wasted junky Bolt !!!Not much of a hangover today with a little time this afternoon ended up as a chuck key for my 4 jaw. Seems to be an odd size of some sort, so I'd been wanting to make one. I grabbed an old bolt from a bunch of hardware I got from an estate and went to work on it. I have no idea where the set screw came from, but it's been laying around for a week or so and needed to be put to use. Nothing fancy, but it works.
