If you have ever tried to drill a hole at an angle with an electric drill, you may have drilled some very shocking holes. To do this, you really need some mechanical help, and this fixture of [kartik_nandrui] should be able to do it.
The equipment uses a guide on the surface to be drilled with a pair of angle connectors suitable for two wooden pins. They connect the guide to a corresponding sleeve which is mounted around the drill body. Then, the sleeve slides up and down on the locating pin, allowing the drill bit to move linearly toward the target area.
This is a useful hacker, but we can see some room for improvement, which will bring it to the next level. There is a way to lock the angle of the guide base, which is very good for accuracy. Since it is 3D printed, it is also easy to create a version with a curved guide base that can be installed on a pipe or other design to accommodate complex geometries, such as roof slabs or other corrugated materials.
Sometimes, the most interesting hackers are those who make us think about our potential projects. If you have any creative tool hackers brewing in the lab, be sure to let us know!
