or so), the silicon carbide refill package was two paper bags, sent
in the mail. I'm almost positive they would have just what you are
looking for: carbide in the large-sand-grain size.

Silicon carbide abrasive is used in grinding optics. any supplier to the
amateur telescope builders will have it in small quantities. The two
i've bought from are Willman-Bell and Salem. Both have websites. I know
they have it down to 60 grit, and likely Salem has it larger.
