I feel this particular plastic would respond better to a blade than
the wet-n-dry but it's given me a thought re making my own?

If I bored said cone in the end of a bit of ally rod then cut a slot
across the end (parallel to one face of the cone) so that I could slip
various grades of grit paper into the side of the 'cone' ...

How about something like this

where the diagonal line is a slot with a bit of tool steel inserted,
with the edge ground like a lathe tool.
