Hi All,
On June 16, Denis Aldrich talked about using Delrin for making combs. I have been making plastic combs for the Chord, 280 Chro, 270 Chro & Miesterklas for many years. Initially, I started using Delrin but then changed to clear Lucite (Acrylic). I have always attached the plates by threading the plastic. The problem with Delrin was that if someone stripped the thread in Delrin you were not able to drill and plug the stripped hole and re-tap it, due to the fact that nothing will stick to Delrin where as a tap can be glued into Acrylic very easily. Also, I was informed by many professional Harmonica players that I had done work for, that they thought the sound was brighter on the hard Acrylic.
Regarding machining, Acrylic is just as easy to machine if not easier and can be buffed to a very high gloss.
