Flattening / Lapping Black Arkansas sharpening stone

[@jamesmiller360]

Good video, I really enjoy using my Arkansas stones and have gotten some amazing edges with them.

[@jrclad2964]

Very interesting and informative. Thanks, Stefan.

Very educational. You started with : IA-46 / F-46 (Aluminum Oxide) 46 Grit, Middle Step : 2C-150 / F-150 SiC 150 Grit Middle Step: IA-400 / F-400 SiC 400 Grit Final Step: IA-600 / F-600 SiC 600 Grit After using it for a while. Do you still recommend the progression you used?

Can you give us the total time from start to finish to lap the Black Arkansas stone? Thanks!

[@MaturePatriot]

What are you using as a lapping surface, 1/2" glass? Was looking for a way to make a flat shop stone for stoning the surfaces on my machine tools. Can't afford $300-$500 for a set of precision ground stones. Great work.

[@stefanwolf88]

Mature Patriot yep 1/2inch floating glass

[@ronfaircloth]

Stefan Wolf what is the length and width of the glass?

[@e.c.knivesandrazors2840]

Does this ruin the glass? Sever scratches?

[@CliffStamp]

With some knowledge of conditioning, these stones are lifetime+, a great deal.

Здрасти Брадли, какъв е грида на самия камък? Благодаря предварително

Do you recommend the same grits for a translucent Arky?

[@douglasskinner]

What are you spraying the stone with?

[@ctdvargas]

water

[@lonelyplanet1080]

using a square rubber mat placed under that glass plate will help reduce that sound

[@michaelrapino4175]

Can anyone tell me ... when using the powder to flatten stones, will the stone match the grit that you use? I see Stefan stopped at 600 grit, but a black Arkansas is the equivalent of over 1200 grit. What is I was flattening something like a soft Arkansas which is equivalent to something like 600-800 grit ... would I only use up to 250 grit powder?

[@stefanwolf88]

I use 150 for my soft, 220 for my hard, 600 for this black which is more of a hard one than Dan's surgical equivalent. Using lower grit is deliberate - faster cutting in the firts sharpening sessions, than it cuts steel as if it it's lapped on finer grit.

[@michaelrapino4175]

@@stefanwolf88 I see ... The stone regulates itself to it's natural grit as you use it? So, with this black, you flatten with 600 which makes the surface of the black fairly course. Then, as you use the stone, the courseness smooths out into the finer grit that the black is supposed to be?

[@westcoastwarriorsarchive7929]

As you use the stone it will wear to its natural grit. Also the silicon carbide grit breaks down as its ground on the stone and glass so it breaks down to smaller sized particles so the longer you use it the finer it gets. @@michaelrapino4175

I lapped my black translucent arkansas from naturalwhetstone this way. Its incredibly hard stone. It took me several hours and I dished my glass. Stone is almost same as in the beginning. Guess i need some diamond plate...

[@westcoastwarriorsarchive7929]

arkansas stones will tear up a diamond plate very quickly. Better to get a granite tile and use the loose grit.

Use some wet/dry sandpaper on a flat sheet of glass.

glue a piece of sandpaper to glass
