Help with flattening Shapton Glass/Gokumyo 20K stones for Edge Pro... DMT 95?

[OhioApexing]

I'm looking to pick up a set of Shapton Glass stones for the Edge Pro, ranging from #220-#16k. I'll probably grab a #20k Suehiro to add to the fun, because, well, I like sharp things and hate money.

Anyhow, what will I need to lap/flatten these stones? Will the DMT 95 lapping plate be sufficient for the whole range? It is my understanding that higher/lower grits require differently sized abrasives to lap properly. If that doesn't work, what will?

Although I hate money, I don't hate it enough to drop $300+ on the Shapton lapping plate.

EDIT: If not the 95 DMT, what about the 120?

Shapton recommends The Diamond Glass Lapping Plate for stones 30 micron/500 grit or finer. A coarser lap is recommended for the 120, 220, and 320 stones. So you probably need at least 2 laps to cover your spread.

T tiguy7 , have you used the diamond lapping plate to level your stones? DM

 

[tiguy7]

Not yet David, but I like to be ready. I have a 140 grit Atoma and the Shapton DGLP which is 300 grit/ 30 micron.

The bottom plate is coarse looking. Is that the 140 grit Atoma? DM

Yes, it is an Aluminum block with a glued on Diamond strip. The storage drawers are from a Festool cabinet.

I use a DMT 95 flattening plate to lap my stones and a DMT Fine 4x1 plate to condition the higher grits, including my Shapton Glass and Gokumyo 20k, and I haven't found any reason to use any other method. The 95 is an excellent tool

Atomas always look coarse because of the "diamond dots" - the diamonds are applied to the plates in small circular clusters, leaving space in between for swarf etc. to escape. The 140 of course, is pretty coarse.
