Hi guys,

Well I've started rough grinding on my 12inch mirror. After applying a rough curve using a grinder I'm now in the process of smoothing the surface and bringing the sag to the desired depth. Just the other day I reached the sag (actually 0,1mm short still), but the edges are not grinded yet (15mm short on average). So my question is, what kind of strokes should I apply to get the edges done, without going to deep in the center. I have used previously a chordal stroke with MOT, but I suspect I should use a normal stroke with small or no overhang TOT. Is this correct?

Kind regards, Darius Blaszijk
