I often have to polish a cylindrical piece, not only for any surface oxide but also to get within tolerance by eliminating cents at a time; (bearings)
Certainly placing your hands or gloves near the rotating spindle is not safe, you can do it 999 times without problems but the 1000th time could be fatal and it's not better to push your luck!
So I decided to build a simple and useful sandpaper holder, to work safely when you need to sand the surface of a piece; the belt width of only 13 mm allows it to enter narrow shoulders.
When the area in contact with the part is worn due to contact, simply turn the thumb wheel to move the paper to another unworn area.
In the first version of the drawing I had thought of a torsion spring, to keep the belt in position: it had remained in stand-by because I didn't have the elastic thread stiff enough at home, however I then noticed that the self-locking nut was sufficient and therefore I decided for simplicity !!
A definite limitation of this device is the possibility of getting close to the spindle, the piece must protrude by at least 30 mm from the spindle, while for long pieces there are no problems!
I would like to make some modifications to the finished piece, but it always happens like this !!
