Quote from: matt sanders on Aug 24, 2014, 12:12 pmDid you get definite dimensions for the diameters that Chris labelled B & D?(Centre bulge of lens, and vertical flange at base). Or do they need extrapolating from your curved profile lines...?
Quote from: matt sanders on Aug 24, 2014, 12:16 pmIs this different height thing definite...? From my Crich mould, I can definitely place the height of the top flange, but the bottom one is set into the metal base, and has been painted over, so it's hard to tell where the glass ends. I had assumed it would be the same height as the top one, but maybe not...
