Making one’s own power tools can be a rewarding way to upcycle parts, and [bluesyann] does exactly that with a belt file made from an old mixer. We like how the enclosure for the old mixer is preserved and acts as a handle, so there’s no need to worry about motor mounting and wiring separately. It looks perfectly usable, and all the hardware needed is the sort of thing one finds in a scrap pile.

[bluesyann] stretches the sanding belt between a 3D printed pulley attached to the mixer motor, and a bearing fitted into the end of some aluminum U-channel. Scrap wood and more nested U-channel make up the rest of the assembly, and there’s even a tension adjustment made from a threaded rod.

There’s a bill of materials and a 3D model for the pulley, but a build like this is more about sharing the broad strokes rather than the exact design. Whenever one modifies or integrates an existing piece of equipment (the mixer, in this case) into a project, most of the work is about working with and around the bits one can’t change.

Watch it in action in a brief video, embedded just below. If you like the idea but don’t have a mixer like the one [bluesyann] used, let us point you toward a similar DIY attachment to get a similar result from a common angle grinder.
