Insomniac Theater: Home made 78 rpm records

We use a 70-year-old disc cutting machine, somewhat modified, to make 78 rpm records on polycarbonate plastic.More information on the machine, the recording styli &c. may be found at http://www.normanfield.com/homemade78... . While most of our recent YouTube videos have been more or less ad hoc, this one is the result of several months considered research & collaboration with my friend Mike Thomas, and tribute must above all be made to the many people who have already made disc recording machines, usually scratch-built, which record on polycarbonate plastic. This is most often done on scrap CDs and DVDs, and at 45 rpm or 33 rpm, and, amazingly, in stereo! Thanks to their work, our task was made easier, as we record only in mono, at 78 rpm, and on 10" (25cm) polycarbonate discs, on a machine that already exists. May increasing success reward their efforts!
