Thread: Naniwa Superstone Lapping Issue

the super stones are resin bound and tend to bow, so that the the edges are high or the middle is high.
The direction of the bow can also change with time as you guys have experienced.

Even the ones mounted on a base are not mounted with more than a few drops of glue (I took my 1k apart when I switched to chosera).
I solved the bowing problem with my 10k SS by gluing it to the back of a worn off DMT, I used double sided carpenter's tape.
