I use this disk sander for shaping some of the thicker parts on my RV-3B. With its 12" diameter, 120 grit and 1 hp, it really does the job. It cuts rapidly and doesn't overheat the aluminum.
After using it on some fittings the other day, I noticed that in the sunlight streaming in through the windows, there were twinkles. Turns out that some of the aluminum dust was airborne. It remained in the air for a bit less than five minutes before settling out.
I had thought that it would all fall down immediately instead of floating in the air, and the accumulations under the sander (which had been vacuumed up before I took the photo) suggested that idea. Turns out not to be so. Wear your particulate mask!
Now whether there's enough dust to be an explosion hazard, I don't know. Anyone?
