I bit the bullet and bought precision ground flat stones.

The last couple grinds on my magnet chuck were out 0.0002". Not enough to stress about, but obviously wiping off the chuck with a rag and a bare hand were not enough to get really clean. My chuck doesn't completely release and it can be hard to drag the vise or part off the soft chuck. It was just enough to cause some trouble.
Stoning the table brings it right back to true
I hand lapped a couple stones on sandpaper that do okay but I don't think they are very flat. They do knock burrs off without scratching up the surface. It's really easy to tell when it works.
I decided to give them a try. Any feedback on these specific stones?
