Welcome Chuck, I am just sending this quick note and will have to try your link tomorrow.
Way back in the stone age I was casting cylinders with a high speed centrifugal mold. The bubbles and other unwanted materials went inward and away from the recording surface. I was using melted down Ediphone cylinders so I am looking forward to reading about your formulations. As for your Edison Standard Model D, WONDERFUL ! ! ! Nothing brings a smile to most collectors as when someone has a Phonograph for a family heirloom. Best wishes, Al _______________________________________________ Phono-L mailing list http://phono-l.org
