My Dremel sanding/grinding setup would benefit a lot from a sanding disk larger than those sold by Dremel so I decided to make my own.
I used the fender washer & 5-40 screw and nut assembly described in my mechanical demagnetizer post...
DIY Demagnetising tool that works
as the basis and glued a 2" diameter wooden disk to the washer. A central hole in the wood provides relief for the screw head.
Sandpaper disks were cut from some self-stick sandpaper and applied to the wooden disks.
I'm pleased to report that they work very well.
