30F3+002+Polishing+the+primary+mirror

Polishing the primary mirror 30F3 002 began on the 31st May 2016 with the making of the lap. Polishing continued on Tuesday evenings and Saturdays when time was available. New 'strips' of Gugolz pitch were poured ready to be cut into squares. These were melted onto the polishing lap that was used to polish the 30F3 001 mirror.

The polishing lap was 'smoothed' out to remove old pitch from the 30F3 001 polishing run and provide a curved base for the new pitch squares.

This is the lap after 8 hours of polishing.
