The Ancient Egyptians knew that the abrasive quality of sand could be employed creatively. As "Daily Life of the Ancient Egyptians" tells us, when cutting a block of limestone to create a new monument, they would pour sand into the saw groove to improve the cutting ability of their copper saws. The abrasive quality of sand, or modern equivalents, as outlined by Stephen L. Wolf is still employed today in sanding discs. These are attached to orbital sanders or electric drill attachments. They can be expensive and can wear out quickly so making your own discs is a quick and clever way to save money.

Choose the grade of sandpaper you wish to use, from fine to coarse. Select a fine sandpaper (less gritty) for light sanding, such as a final sanding to an item of furniture before staining. Choose a coarse sandpaper (more gritty) if you need to remove more material, such as when fitting a new door.
Turn the sandpaper over. Place an existing sanding disc on the paper in a corner so as to minimise waste. Draw around it with a pencil. If you have no existing sanding disc, you can use the head of your orbital sander or drill attachment instead.
Draw and cut out the central hole that some sanding discs have, if applicable, using scissors or a craft knife. I've you'll use the disc with a sander that features dust collection, draw and cut out the dust-extraction holes that match the holes in the base of the sander.
Cover the back side of the sandpaper with overlapping strips of clear packing tape to reinforce and stiffen your sanding disc. Cut tape away from any dust-collection holes you cut in the paper. Cut out your sanding disc following the pencil line.
Stick a Velcro backing to your disc if this is how it attaches to your orbital sander or drill attachment.
Tips and warnings
- At Step 3, holes can be cut after applying clear packing tape, but this is slightly more difficult.
- At Step 4, you can choose not to reinforce your sanding disc, but it won't last as long.
