As is often the case, I’ve gone in a slightly different direction. This is a Guinevere cable drive, powered by a stationary motor, or in my case a defunct craftsman lathe headstock.
I find two advantages over using a drill as a sander. First is noise. A lot from the drill and almost none from my set-up. (I find that high noise levels in the shop add stress and reduces the amount of time I can spend without fatigue)
The second thing is handling/maneuverability. I’m comfortable handling this overhand, underhand or like a pencil.
Its fitted with a 3inch soft sanding pad and Norton 3x disks.
The restrictions are that it only goes forward. If your lathe reverses, that isn’t an issue. If you push hard, which you shouldn’t, the cable wants to wind up.
