Finally after just over 100hrs work spread over nearly 10 months I've finally had my mirror tested for the first time.
There are good and bad bits.
Good:nice spherical curve and no turned down edge.
Bad:it has astigmatism in the form of a depressed centre.
John tells me this is due to not polishing through centre and not turning my mirror enough but says it should polish out hopefully.so I'm going to do a couple of hours polishing through centre then 're test and see if it's better if not I may need to go back to 600 with the tile tool and do some more through centre work.all in all its no big deal and I'm pleased with how well I've done for my first bring.need to get my tester finished now so I can see how I'm altering the shape with my through centre polishing.
I'm on holiday in a couple of weeks but hopefully November with be the month I start figuring!!!
Wish me luck!!
