I rarely lapped my 500 grit ceramic stone since I have not had much use for it. The large majority of my lapping has been 4K grit or higher.

I still have my D8C and I use that for coarse stuff. A friend of mine said that Shapton suggests only lapping their stones. I figure that is because they can't be sure of what the grit is on another manufactuer's stone. I have also lapped coticules, and Eschers and no worries so far.

The re-manufactured lapping plate that Shapton offers costs $325.-00 so it ain't a bargain. The steel backing being the more expensive component is for flattening planes. Harrelson said that if you drop it can go out of true so the GDLP is probably the best bet of the Shaptons for lapping. I imagine if the diamonds don't last in the glass plate they won't be any better in the steel. Let's hope this is a defective plate and not the norm.

OK, no tool is perfect and the limitations of this hone are now being seen.I also hope that this is an anomaly. Time will tell.

Since Shapton has a work around they must have expected this but a better response would be to offer a resurfacing at the factory. It would instill a lot more confidence that the job was done right and the flatness preserved. The flatness of these hones is the main selling point for the guys in the straight razor world. I hope Shapton realizes this.

Just my two cents,
