So in an effort to stop buying stones i have started making some synthetics. I am sure i am not the only one to have tried this. Pretty sharp learning curve but i am at least at the point where they do not disintegrate when i lap them. First picture is two smaller ones i have been testing. About 4x1.5. Did some quick honing just to see some scratch patterns. First is shapton 8k, next is the white stone, last is the green. Both treetop arm hair right off the stone.

I don't want you to give away any trade secrets but I wouldn't mind hearing more about your process.

I'm sure you can guess the type of abrasive in both of those stones by the color. Right now i am playing with easily available abrasives in a magnesium binder. Pretty much mix, mold, then cure.

Still trying different ratios and curing processes.

My original plan was to make a large wet grinding wheel like what you see in japan. These smaller stones where to be test pieces. So far i do not think the current binder will scale well into a large wheel. But it is still the beginning of the journey.

If i had to guess by looking at them, i think his are a shellac or resin binder and a much better quality of abrasive. I am using rock tumbler abrasive until i get the binder and the process sorted.

I, for one, might need more info than that. Pretend you are making a cake. “Take some flour and ****, chuck it in a pan and bake,” isn’t a cookbook going to make.
You started the thread…

The abrasives are mainly SiC or aluminum oxides. The green one is chromium oxide. Still formulating the binder and curing/firing process. Just made a very rudimentary vacuum chamber to try to remove as much of the air as i can.

Interesting observation with the SiC, wears faster and leaves a very hazy finish.
Be very surprised if this is worthwhile to make standard bench hones... now custom shapes and sizes that you couldn't easily cut out of a base stone, but COULD mold... for very specific purposes... Very intriguing idea.
I have. Many types of hones over the years. Still working on the project actually.
That said, I was told, in no uncertain terms, that I was not allowed to discuss them on B&B.
I had started a thread back when I started, it was removed.
Ironically, the title was nearly identical to the title of this thread.
Making a sharpening stone is fairly easy once the science is fully understood.
Conceptually, it's like baking a cake but in reality it isn't like that at all. It's not just binder plus abrasive. Understanding covalent bonds, for example. There's a lot more to the recipe than just the ingredients.
I just rejected a .1 monocrystalline diamond abrasive for reasons I wont get into here but it's a shame and it took a lot of effort to get something to meet spec and it didn't fly.
Making a brick is like making a cake. I can sharpen things on a brick though. But do I want to? Nope.
Making a quality sharpening stone, for me anyway, is more like creating complicated fine pastry.
Making one that is better or even equal to what is available is less easy.
Making one I want to use is harder than that.
Making one I want to use, consistently, is at the edge of sanity.
If I had a real lab, and an outfitted factory with proper ventilation, then some things would be easier. Kitchen table chemistry only goes so far.

Well that isn't good. I've never had a thread pulled before.

I looked at the titles of the 220 odd threads you've started here and can't find it. Are you sure it was here?
Could you please give me any further info on it by pm? Time frame, discussion on it etc? Anything would help.
If it's beneficial info and not commercial (which is the only reason I could think of which might cause an issue) then it ought to be out there and readable by the members.
I posted a link to a thread on another forum where a guy was making his own stones. Real interesting too. It was 6 pages of content covering 2 years. His progress through various compounds, resins, techniques, suggestions from other members. Way too much content to repost here. I thought that would be helpful to someone here if they were also (wait for it….) making their own stones.
But it was deleted by the mods.

Was def a B&B thread.
The discussion was in its infancy and not worth digging up IMO.
I think situation revolved around a misinterpretation.
I only brought it up so someone/s understand one reason why I don't get into specifics on this topic.
Some other reasons include safety concerns that are often overlooked. Very serious dangers can exist here.
Sorta like another hobby I have, working on tube amps.
I don't get into specifics with that stuff either because I don't want someone to follow directions, but goof, and die.
Yes, that can actually happen.

I read it so just a quick summary without linking. Two part epoxy mixed with diamond powders to make a stone. Other abrasives don't seem to work will. Larger grits sink to the bottom of the mold so less epoxy more grit. Small grits stay suspended. That is a very broad stroke of 6 pages of content. There was also some discussion of sodium silicate, water glass, as a binder but it is water soluble.
