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.

Pics to follow

Not an option fella,I have to do it myself.it was John who said i should polish for a bit then go back to 600 if the astigmatism didn't polish out

Shame that Rich. I need to send some Ronchi images to John see how he thinks mine should progress? I am thinking of ordering the ply and truss poles for delivery next week fella so will be able to make a start on the dual build so I'm sure you'll have the mirror sorted before its finished!
