With the basic layout of the sanding station completed, I next turned to designing a holder for sanding disks. Ideally, they would store flat with a weighted plate on top to keep them flat, but that didn't really work with my plan to hang them from pegboard. The next idea was to have an open top thin box which would work very well when full, but with only a few disks in the box there would be room for them to curl. so I needed a solution that would keep the disks flat with one or twenty.

My solution was to create a shallow frame. The inside dimensions are 5 1/4" to accomodate the 5" disks (make it 6 1/4" for 6" disks) and about 1 1/2" deep. The sides were notched at an angle to accept the front. The front not only holds the disks from falling out, but as disks are removed, it slides down the angled notches in the sides maintaining pressure on the disks.

The front part is 5" square. I cut it with attached ears that were then rounded to 3/8" diameter using a dowel cutter, but it would work as well with dowels glued into the edges. As long as it slides down the angled notches freely, it will work. The back is nothing more than 1/4" hardboard glued and nailed directly onto the back edges of the frame.

Obviously, this was a fairly crude prototype. The hardboard back needs to extend above the frame so holes can be added for the pegboard hooks. A finger hole should be added to the face as well to make it easy to remove. I will upload final plans for making all the holders as I test them out and make sure they work as designed.
