Thread: Unsure about lapping

I'm most likely going to get another duosharp extra fine...That's what I broke. I thought I'd be able to just get this 120 micron id be ok, but that proved wrong. Lol. Thanks guys.

When flattening my 8,000 & 10,000 grit made in China hones I use a King 1,000 - 6,000 grit hone to finish them & it works well for me. I set bevel with either the 1,000 grit side of the king or a 500 grit belt on my Work Sharp blade grinder. I keep the belts very tight & put almost no pressure on them & that has also worked well for me. Yes I can get a razor to pass the HHT on my work Sharp. If used properly I can take my razor to 6,000 on the Work Sharp blade grinder & then use my 8,000 & 10,000 grit hones, strop on canvas or Balsa & then finish strop on a shell horse hide. & get all the edge I need.
Back to flattening stones I have a American slate I am working on & for some reason having a hard time getting it finished the way I want. Any suggestions??

Doesn't matter what grit the diamond plate is, when they are brand new they will really tear up the surface of a stone. After they break in and the diamonds are worn down a bit then it won't make much difference what grit the diamond plate is.

The issue is this: when the diamond plate is new it has very sharp pointy diamonds, and they leave sharp trenches and peaks, both in the shape of a 'v' - after the diamonds wear to a rounded or slightly flattened shape these v's are truncated and have plateaus at the top and bottom.

When the scratches are made in the 'v' shape, it's very easy to break the tops of the v's off as soon as you start honing because they are fragile - then you end up with a very light loose slurry on top of your stone - this cuts fast as all get out, but leaves a rough finish. After the v's are plateaued, the tops don't break off like this so you don't have that loose grit rolling around - hence the stone cuts a bit slower and gives a better finish.

I think you are talking about,120 grit or mesh not microns.

Take a look at the CNTG 400/1k dual grit diamond plate for $35. The 120 will get you flat the 400/1k will get you smooth.
