Thread: Recommendation for a super fine 0.2 Micron Polishing Compound

How about automotive cutting compound?
Is it possible there was some sort of contamination of the Veritas compound that caused the scratches?

Send an email to Tormek requesting the info you want about there polishing compound.

As I need to polish some very fine scratches out of metal caused by Veritas Honing compound which is at 0.5 micron.

I have seen diamond paste but that seems to stop at 0.5 micron I did a quick search and found 0.2 micron abrasives used for Jewelry polishing. I have however no idea if these Jewelry polishing compounds are any good or suitable.

The other option is a synthetic Japanese waterstone at 12000 and 30000 stones. sold here by soatoz - how fine a micron would a 30000 grit stone be. Also I do not need a whole stone so if I could get a paste or even a fragment at 0.2 micron it would be much better.

The other concern is the cost of a 30000 grit stone which is over $550 dollars.

I would greatly appreciate any help on this mater.

Dan I had a look at Veritas Honing Compound and found maybe a grit/dirt on the outside, so I scraped it off and added the clean compound to the clean soft leather.

It is doing a slow job of removing the damage.

However it is still not fine enough to match the super fine polished metal.

Dan can you recommend a automotive cutting compound that is good, I had a look and found kitten cutting compound is that what I need.

On this page they list dozen of cutting compounds which would be the best for me. Water and Wax free would be best I think.

If the cutting compound is still no enough I will have to use something more finer.

Any idea on the micron rating of an automotive cutting compound?

It was just a suggestion. You'll have to give it a try to see if it's what you need. Any sort of cut and polish would be a good place to start. What are you trying to polish?

Look for lapidary suppliers, they have grits as fine as 100,000 and more, or should that be less?

I used to facet stones and you have to use some very fine grits indeed to get the polish on a rock.

Maybe Brasso; or Autosol (from an automotive supplier like Autobarn or Repco).

Going to be a bit of suck it & see to get the desired result.

Firstly I would ask why?

then
there are a number of compounds used for metal polishing available in bar form from machinery suppliers like hare & forbes.

Lapidary is a good thaught.

the untimate in sharp is superfine diamond paste on glass, a friend of mine trained in pathology & they sharpen their knives that they use for preparation of microscope sections on glass with superfine diamond paste.
Where they get it..... who knows.

I'd be looking at the finer polishing compounds

I don't think the automotive compounds would be hard enough.
Anyway.... any decent auto refinish supplier will supply you micro fine finishing compound in litre bottles for about $16.... there are three grades
I use medium to polish my acrilic.

cheers

Try 3M "finesse it".

Why not try the Veritas green rouge again? This time make absolutely sure that the medium holding it is free of any grit. Otherwise can you be sure that this will not be repeated with other (finer) honing media?

The other thing you can try is to use the green rouge on a spinning cloth wheel. The speed increases the honing action.

I am going to do what Derek recommends by placing a clean carved block of veritas honing compound into a soft cotton cloth and melt the compound a little and polish it through the cloth. Like French Polishing.

I have found a Lapidary in Mentone who has a large range of polishing compounds for steel. Aluminum oxide is recommended for polishing steel, it is sold as a fine powder which you blend with oil or water.

Wish me luck.

I got two polishing compounds from the Lapidary.

The first product is Hi Pol which I would say is less then 0.4+/- micron, then Linde A is even finer, I managed to polish the blade down. To an even polish.

I am told they are both, Aluminum Oxide formulas, and I would be interested to know how they would go as as sharpening compound.

And how was Darren at Dazlen Gems?

Hes a nice bloke and easy to deal with.

He is a very nice guy, gave me the coarser Hi Pol stuff as a sample for free, just incase I did not need it. I now have a tone of abrasive.

May have to start making knives.

Dont forget to post some pics..

I too have knife making in my sights....
