    Need demo/pattern for Caviar 6527

    I have a customer wanting plano lenses installed in her Caviar 6527. Anyone in the wide wide world of optical have a pattern or original lens I may duplicate?

    Mick, you been at this since we ground lenses down on Fossil Creek with smooth rocks. Get a piece of paper and feather trace the eyewire part and improvise the rest. Transfer to a pattern blank, cut it out with tin cutter pliers then run a demo and modify from there... Easy peasy.

    Place the frame on a copy machine, cut out the shape and transfer the cutout to a piece of cardboard. Then you can trace it like a demo lens.

    I can remember when Weco had the best pattern maker on the market. A punch cutter that deformed thin frames. Worthless paperweight. We did exactly what Optical24/7 said. Faster and more accurate than the Weco!
    Then there’s this. When I started centuries ago in San Diego, we bonded lenses in dive masks. Every single mask needed a custom pattern, up to and including Franklins. No pattern maker was able to do it. It was up to me. Dive masks were my responsibility. Hand pans. Saddlebacks. Custom patterns. I shouldn’t say this, but, sometimes, I miss those days.
    I bend light. That is what I do.

    It appears that this frame is missing lenses. There's nothing there to trace. The OP really needs a pattern here, not a method to create patterns.

    The string really makes it difficult to trace. I like the copier idea, I think that will work or free form the temporal side as the string will follow most any shape you want.

    You can google search the frame to find images to work from. If you trace the frame side of the lens onto paper, you should be able to extrapolate the rest of the shape from the image; it's not at all an exotic shape. You may find that the lens you cut is a bit large or small, but just adjust the rimless liner as needed.
