home made 78 rpm records

We use a 70-year-old disc cutting machine, somewhat modified, to make 78 rpm records on polycarbonate information on the machine, the recording styli &c. may be found at . 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
