Of course there is a supporting story, it was all about getting the sandpaper out of storage and arranged to use in succeeding finer grit application on a bicycle sanding project requiring both alu-oxide and wet/dry.
The situation:
Curly sandpaper from exposure to moisture, and picking up odd/n/end pieces from garage sales, etc. Yes, they were "mostly" organized but stacking was impossible with them curled.
I've found this to be helpful:
Alu-oxide curly sheets can be successfully straightened with a LIGHT spritz from a squirt type sprayer bottle of water. The sheets will quickly curl again, but have two flat plywood (or other absorbant) pieces with weights handy to press flat. Drying is fast. Sometimes 2 spray applications are needed.
Wet/dry generally stores flat, but flattening follows the above process.
Once straightened, they can be nicely stored and retained in the flat USPS boxes you get for free at the place with ugly square trucks painted white. Nicely notated with grit sizing of course. Once flat, I put them in manila file folders inside the already flattened boxes.
Easy peasy
