Rocky,  Why the abrasive in the card stock? Was that to keep the brushes clean
as cards passed them?Bob

Advice: don't ever use sandpaper on points. Even a stone is at least slightly
suspect. Grit can get embedded in a point. IBM provided us with a "points
file" when I worked for them in Toronto back in the 60s, but our favorite fix
was an IBM card, since the paper had a tiny bit of abrasive built in.
