        Gil asked: "Art, how about a picture of your lap"

        Hi Gil!

        As I explained in a previous response, the lap was chilled in the freezer and then chipped from the tool to be reused later.

        However, I have  posted three photos taken of the rubber mold made from soft 5/16" material. It appears that may be too thick. I'll order some 1/4" and 1/8" material from McMaster.

        I came a cross a precaution from Gordon that if you are low on experience, these pitch laps are best used for aggressive polishing not for final figuring.

        Given my experience level and the fact that I intend to use this 10" lap for smoothing the final figure on a 15" mirror, I'm wondering if perhaps I should fall back to more conventional facet geometry.

        I'll try it and see. Before I pour the lap, however, I must finish setting up both the Ross Null and Foucault tester.

        Happy New Year

        Art
