Thread: Has anyone used lapping grit to flatten stones?

I am trying to flatten a Norton 4/8K stone with silicon carbide lapping grit. I put some grit: 280 on a granite tile with a sheet of plastic on it, add a little water to make a slurry and move it in a figure 8 pattern. On the 8k side I got the stone smooth, but the 4K side is flat but I can't seem to get it smooth. I have spent some time on it. Does anyone have experience with this? I thought maybe there is something I am doing wrong. I know the 4K can get smoother.

Thanks

The 8k is rather a hard non-porous hone so it reacts rather well with lapping grit, however the 4k is just the opposite and very porous and works better with sandpaper or a diamond plate

This makes me wonder if my 4k is as smooth as it should be since I have never felt one that is where it should be. I used a dmt d8c and made it flat, but so far haven't had problems honing on it so far. It seems to have that soft feeling when you run your finger over it.

A very handy tool for one's honing arsenal is a Nice CHEAP 4x1(about) Arkansas stone lapped too smooth, you can use this as a Nagura/slurry /smoothing stone for just about any other stone out there since they are so hard... I got mine for .50 cents at the flea market just clean them up first as most are oil soaked.

+1 .... I also use a #102 Carborundum Razor Hone as well for a Nagura/Slurry/Lapping stone. It's about the same size...and It's hard as the 'proverbial rock'!

Great idea. I use one of my PHIG's to refresh and smooth out my synthetics.

I used my Spyderco UF with 0.5u diamond spray to flatten/polish my Charnley. Question: is that too smooth to make a hone?

There an issue in the past with the Nortons needing considerable lapping to get to a workable smooth surface.
