Would this work with JNats or softer stones. I know Shapton has a smaller version of this.This also works well. Forgot i even had it until the other day. Roughly 6x4x2 cast iron lapping plate. Done two hard arks off this so far and both where very flat off the plate.
All my Jnats are hard finishers but one. Yeah, diamond plates are the way to go. I may get a lapping plate for my Arkansas.It would but i am not a fan of loose abrasives on jnats. Not unless they are super hard. I always worry about embedding SiC in the stone. One piece of 60 SiC stuck in the stone surface can make for a bad day
You can use really fine play sand on those as an abrasive. Iron bands with fine sand is what they used to cut coticules with(they still might, I don't know but I doubt it)This also works well.

The silica sand that i have feels finer then 60 SiC. Worked pretty well on some slate tho. And the price was right. Just hate how it gets everywhere.You can use really fine play sand on those as an abrasive.
