Setting a bevel with sandpaper
I'm taking another crack at using sandpaper to set the bevel on my stock of eBay specials, but I've run into the same problem that led me to quit using it last time.
I taped the spine on this 6/8 square point that I'm working on, and got a nice, clean bevel with 800-grit wet-dry sandpaper. (My stock of 1000 was out, but the 800 seemed to work OK in a pinch.)
Then I took the tape off and did about 50 laps on my 4K Norton. Under the microscope I can clearly see two bevels. So I do another 50 laps. Some progress, but not enough.
I thought maybe the electrical tape had thrown the edge geometry off, so I tried some laps on 2000-grit sandpaper without tape. Again, nice, even bevel. But when I get to the Norton, it develops the double bevel again.
I think the sandpaper is rounding the bevel slightly, and it takes forever on the 4K to get it flattened out.
What can I do to prevent this? I soaked my sandpaper and stuck it flat on the 8K side of my Norton. I guess I could glue it down, but I can't imagin glue getting it any flatter than it is right now.
How do all of you guys who use sandpaper avoid this problem? :shrug:
