Hi everybody.  I have a number of Polyphon discs that are missing a
great many projections due to rust and mishandling.  Does anybody have
any ideas about how I can go about replacing these without going mad ?

I have read about a few methods in various books, such as using cut
staples and epoxy (yuck!), and have a gut feeling that surely something
easier, more accurate and elegant must be possible.  Any ideas ?
