do you have powder, paste, spray, loaded discs or cloth? diapolix sells the powder for 50 cents a carat, but it's a 200 carat minimum. Not sure how far a carat goes, how much is in low/med./high concentration syringes, or in the pump sprays.

I have diamond abrasives up to 100,000 grit. At 1/4 micron, it really does not do anything better than 1 micron (14,000 grit). Except when doing a faceting job ( cutting gemstones) for a competition, I rarely polish beyond 14,000 grit. For a competition polish I use 50,000 (1/2 micron)

For sharpening/polishing steel blade edges, 100,000 grit is far finer than the steel grain, and won't get a blade any sharper. If you are a fanatic, polish to 14,000 grit with a diamond paste on a sheet of glass. Beyond that you are getting into obsessive compulsive disorder.

Think of it this way, If you took a piece of concrete and started grinding it down , it would become smoother, but at some point the size of the grains that make it up would be the limiting factor that would end any further smoothness. It is the same with steel, just a bit smaller grains.

you should hang out on this sub forum more often, you just told a Weight Watchers group that they like food :D

I was thinking of getting the 100K diamond because I like using 0.5 micron CrO at the moment - but to polish up my ZDP-189 caly jr, or for any 10V, S90V, or S125V that I may end up with in the future - I may need diamond at this fine level of polish. I could get 0.5 diamond, but I figure why not go a little finer with the faster cutting material.

Well, I use 100000 to make top steels - ZDP189, CPM S90V to whittle hair. I am doing this on regular bases and think that this has nothing to do with grain size - because it just sharpen those grains.

Is it correct thoery or not - I do not know, but I can assure you that without 100000 mesh diamonds thise steels does not whittle hair on regular bases (sometimes they does sometimes does not) and with it - they does for sure. This is my first hand personal experience.

Thanks, Vassili.

I think that you are very right. This is my expirience also. But for me 1 micron is enough with any steel. I can make Opinel split hair like ZDP189 and also cheap chinese poket knive. Split hair is esy bit to make edge last is a bit more hard.

Yes, softer steel - easier to make it hair whittling sharp. Most of the steel get that sharp with Green Rouge, probably because CrO hardness is enough. But for hard steels ZDP-189 65 HRC, or steels with ard Carbides - vanadium carbides like CPM S30V or steels with both like CPM S90V it is very hard to sharpen to that sharpness with Green Rouge - sizes of Carbide particles is bigger then required and to sharpen-shape them (particles) smaller size diamonds needed.

It is interesting that diamonds with bigger then 100000 mesh does not work, may be I have wron diamonds or may be abrasive size should be times less then carbides size to successfully shape them.

To me quality of steel is not to wha extent you can sharpen it, but how long will it stay that sharp.

Thanks, Vassili.
 
The size in microns for diamond paste is an average. For example Congress Tools lists their 1/4 micron paste as having a particle size of 0 to 1/2 microns and their 1/2 micron paste as 0 to 1. Thus a 1/4 micro compound may actually be producing a 1/2 micron finish. (Note: I have never used below 1 micron, or actually 0 to 2; and have no way of actually measuring the sizes.)

Also, you may want to have a look at http://congresstools.com/ as a source of diamond paste, etc.
 
found a site willing to sell me 50 carats. now to figure out how to apply it. cardboard, mdf, leather, paper, mixed with CrO paste, on 0.3 micron alox lapping film...
