Just like tires, worn out Velcro- backed sanding disks can be given a second life by gluing fresh stock onto their dull surfaces. This Instructable will demonstrate a reliable and inexpensive way to refresh your old ones so they may perform better than new in some cases.
Begin by making a template based on the desired size and marking the material out, in this case I wanted 5” (127 mm) rounds. I purchase inexpensive bargain box mill- ends from an abrasive house and use this top- quality stock for all my disk sanding needs, as well as square ¼ sheet random style and also hand sanding blocks. I’m never without the proper grit I need at any time day or night.
