Morning All,
        Careys updated our web site regarding the pitch channel cutter as well
as
putting a pictorial record of my polishing sessions up. There are photos
taken with a 50/100? LPI screen, a 133LPI screen and a foucault at the
centre of curvature. So far my polishing time is 11 hours and twenty
minutes. The blank is highly polished but just the wrong shape in
places...........
        Click on the link in my signature and then click the link titled
"Newest
Feature". This will take you to the updated pitch channel cutter. At
the bottom of that page is the link to the ronchigrams and log. Cheers
