Thread: My little lapping stone.

I picked this up from a former quarry/stone manufacturer that shut down. I still don't have the system setup so I can leave it alone, I have to feed the Grit by hand. But hopefully when I get time I will get something figured out. I know how it was setup originally but that just takes up even more room. The table itself is 4 feet, and the cast iron disk is 32"




The brick is just there because I don't have the dividers adjusted correctly. The smaller stones get caught under it and get broken,

Very cool! Is the powder just sand? Or some specially formulated lapping powder?

Yes it's special powder, I purchased it with the lapper. I don't 100% know what it is, but I paid 50 bucks for a 5 gallon bucket that was 3/4 full. hell it might be old Ark'y dust for all I know. I can reuse it for some time, as it collects in a bucket. Eventually it will get worn down and turned to a very fine powder. Which is still cool, becuase I can then have several grades of grit.

Silicoln oxide I assume. I think that is what they told me.

Then when I got the lapper home and lifted the lid I found another 10 gallons of powder inside the machine. So I probably didn't need to buy the first bucket, the seller didn't know it was full.

I wish I knew how to sift it and separate it by grade. I use a window screen to get the big particles and broken pieces of stone out. I have seen brass sieves online but I think those are still to big to do me any good. I am new at this so certainly no expert.

I'd normally say that that is overkill, but I've seen the pics of all your Arkies and other hones. In your case it might not be enough.

That is so cool!

Nice machine but noisy I assume No need to lap the sides of the stones.
