Willie,<br><br>Emery cloth is made with a fine grained impure aluminum oxide (maybe garnet?). It would be OK, I think. Try it out and see how it works. It's a classic for polishing metal, so it should work.<br><br>The wet-or-dry paper I was refering to is black - silicone carbide is the abrasive (harder than emery). As for grits, try combos of 220 and 320, 320 and 400, 320 and 600 - those are just suggestions. Contact cement seems to work fine.<br><br>It seems to me that the aluminium oxide papers loose the grit faster than the silicone carbide papers. If the silicone carbide paper is used wet (water), it seems to last a long long time. Funny thing - when grinding tool bits, I use aluminum oxide for tool steels and silicone carbide for carbide bits... but that's my experience with sandpaper for sharpening; the silicone carbide works better for me.<br><br>3M makes diamond dust sand paper, BTW - I bet it's spendy...<br><br>Regards,<br><br>Tom
