I actually tried this when I wanted a grit for my Worksharp 3000 that wasn't available from the factory.
Use any desired grit of good sandpaper and used the glass or slotted plate as a template to cut out a circle with a razor or Exacto knife. Back up the sandpaper with a scrap board.
When you get a nice circle of sandpaper, lay it sand side down on a piece of newspaper and spray with contact adhesive spray. I use 3M #77 available at most hardware stores (it also has a lot of other uses in the shop).
Let the adhesive dry for a few minutes and stick it to the glass plate of slotted disc. Press the paper tightly to the disc and use the impression of the hole to cut the center hole from the sand side.
If you are using a slotted disc; press it on a backer board scrap as backup and use a razor knife or Exacto to cut along the edges of each slot; then poke the blade on each end. No need to cut the ends fully, just weaked it with a cut of some sort so it tears neatly. Push the slots from the sand side and pull them off at an angle to the side. This tears the scrap in the slot at the ends and pulls the paper tight to the disc.
I've made a number of these, mostly for the slotted discs (about 10 minutes to cut one - faster than going to buy one too) and have had no problems.
Be sure to clean the discs well with alcohol after removing an old disc. I failed to do this once early on and it didn't adhear well. (until I cleaned it with alcohol and used 3M #77 on the old disc - Then it stuck like glue (Sorry!)
