I dig homemade tools. A lot. They’re a labor of love that eventually save you time with other labors of love. They’re typically a heavy time investment up front, that only one person – the maker! – gets rewarded for. And they’re always a little bit unique. I have some custom drill bit holders, cases, and coupling mechanisms, but have always relied on either guessing a drill bits size and hoping for the best, labeling its size onto it if I think it’s an odd number I’ll need to remember (like 7/32), or using calipers to measure. I like calipers, but they require a battery and for that reason alone I’m digging this custom analog drill bit gauge from Instructables user Caspar, built from an old ruler. As with all custom tools there’s some adjustments to be made along the way depending on your needs, but maybe this tool eventually saves you some time later. It’s definitely going to amuse and bewilder anyone who looks at it!
