big dilemma
Well I have now done about 15 hours polishing with nearly 10 hours through centre and I still have the same problems as before when the ronchi image flips through.when looking at the ronchi I don't get the same obvious centre circle as before but still showing the centre astigmatism.I'm pretty much doomed to going back to the tile tool and doing a few hours with 600 alu oxide to get it back on track then start polishing again.I could keep polishing but if it's not changed after nearly 10 hours I think it will be quicker to go back to 600.the only other option is to polish out which Wil probably be another 6-8 hours then try and sort it when figuring with the smaller tool.
I'm erring towards gojnng back to 600 at the moment.
