Thread: New 1/2" sanding mandrel tutorial.

Let me see if I can remember how this is done.
1. Take a sheet of sandpaper and cut a strip 1.57 inches wide
2. Take a 1/2 inch diameter rod (I think he used an acrylic rod) and lube it up with wd-40 or some other light oil
3. Wrap packing tape with the sticky side out around the length of the rod spiraling downward in a clockwise direction.
4. Stick sandpaper to tape.
5. Roll sandpapered rod in between your hands to make sure that the sandpaper is stuck to the tape.
6. Pull sandpaper tube off of 1/2 inch rod (now you know why you lube the rod up)
7. Cut the tube into lengths that you need.

I've had good luck doing this with fabric based carpet tape, but switched over to just making 1/2 inch cardboard tubes and contact cement the sandpaper to the tube.
