Summary
Creators at ProShorts 101 have shared a video on YouTube showing how to make a disc sander using an old hard drive, adding a few other elements to transform it into a working tool.
The video shows a hacksaw being used to cut a hard drive in half, before adding glue, wire and a battery pack, with the speed controlled by a potentiometer.
Comments from users on the video include what type of glue was used and the best tool to cut sandpaper without reducing the sharpness of the cutting implement.
One reply highlights that a 3-inch diamond grinding disk could be added to the spindle for fine honing of carbide lathe tools.
Another commenter suggested gluing velcro to the platter on the sander, enabling sandpaper to be easily replaced.
