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.
Step 1: How To Proceed
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.
Step 2: Make A Variety Of Grits
Next I cut the disks free and also salvage any straight sections from offcuts to keep in my shop apron pocket for on the job minor touch-ups.
Step 3: Assemble The Two
Using construction adhesive, I attach the new disk to the old ones I have collected and saved for just this use. Dead weighting under a pressboard for about ½ hour is plenty to ensure complete bonding.
Tip Within A Tip: See the black electricians tape at the end of the glue nozzle?
I slice inline back from the tip about ¾” (19.05 mm) to eject the dried slug from previous use, then re- tape for a good as new free- flowing applicator tip. I can find partially used cartridges at yard sales dirt cheap, or in roadside refuse for free and this trick allows for total use of the contents.
