Can a Atoma 1200 use as a lapping plate for the 30K stone? I read some where that Atoma 1200 is not good for lapping, what other plate can I use for lapping the 30K beside the Shapton's brand lapping plate?
Thank you.

The DGLP is actually a 325 grit
So the 1200 as long as you have already knocked off the high diamonds will be fine
Keep in mind the no lapping warning is there so you don't think you can lap a few Akries and not wear down the Diamonds
Lapping soft (in comparison) synthetics should do no harm
ps never lap hones that are near or lower grit than the plate
Water water more water
Glen,
I more than once lapped a JNAT with a 400 Atoma plate and could not figure out where the scratches came from then it came to me after getting them out with a tomo and the next time I lapped it I noticed scratches so now I use a pretty worn down 1200 Atoma when needed and then burnish the stone with a tomo to smooth it out, as for the rest I use the 1200 and on the 1K I use the 400, both plates are pretty worn and I have not seen any ill affects so what can happen using a lower grit plate on a hone as long as it’s worn down and not new.
The other way around :)
If you lap a 1000 grit Hone with a 1200 grit plate you can tear the diamonds out of the plate
same as you don't lap anything less than 800 or so on the 325 plate

The question about the shapton's lapping plate is because I didn't know it's that coarse otherwise I wouldn't bother asking about it since I do own the Atoma 140 and 400, no need to explain to me why I shouldn't use a high grit lapping plate to lap a lower grit whetstone.
My question is what should I use for lapping shapton glass 30k stone, please keep it simple.
Can I just Lap the Atoma 1200 on a Shapton Kuo 320 to break in the Atoma a little bit?

Your 400 would be ok too
Ps: I am also assuming you have already done the heavy lifting by getting the 30k grid flat with your lower grit plates and now just need to smooth the surface before honing a razor ..
The quickest way to break in an Atoma is about 30 seconds on a Spyderco UF...if you have one.
Break in is hardly needed. Out of my 6 Atoma only one ever had a high spot.
IMHO the 1200 is no good for flattening as it's too fine to remove much stone but for slurrying & daily cleanup on fine stones it's perfect.

If this is the case, can I use another whetstone to smooth the 30K out or it's too hard of a stone for it to take effect?
Try the Atoma for a few laps, just short strokes. If there is no obvious high spot just go ahead & use it. As I said tho, the 1200 is not the tool for flattening an uneven stone. The 400 is a better choice.
I probably don't need to tell you that as with honing, lapping is best done with a progression of grits if the stone is really uneven.
With the little to no pressure needed on the 30K. hone. After you get it flat the first time, it should be good for a l o n g time! My 16K Shapton stays pretty flat.

Thank you guys for helping me =)
