Comment on Sandpaper Adapter for Oscillating Multitool

That is interesting. I’m professionally curious about the drive mechanism for the oscillation pattern on these now. As a former auto body shop owner and painter, I would not expect this to be free of mechanical error like a high quality pneumatic dual action sander, but it is an interesting idea. In fact I can imagine taking this to another level and creating a thin sanding blade like design with Emory paper, to use in very tight slots.

Does mechanical error actually matter when using sandpaper? It seems like most of the error comes from holding the tool with your hands.

It does matter for automotive-class perfection. You will have hot spots develop that dig deeper than the rest of the surface. We are talking about mirror gloss perfection though. You are likely not working on a project of this scale/class.
Patterns can emerge from resonant frequencies (www.youtube.com/watch?v=wvJAgrUBF4w). The dual action of a “DA” sander is made to cancel out the resonance.

You can buy these from Dewalt with triangular shaped velcro backed sanding pads. I used one to refinish a crappy bedside table during covid and it did leave a lot of weird sanding marks (especially if the paper picks up any debris) but it does work. It’s probably better suited for small surfaces that aren’t flat.
