Rapid prototyping of Chromatic harmonica coverplates

[@danielabbey7726]

Very interesting process, John. Will make a mental note of this for future projects!

Another fascinating video John, thanks for sharing!

Thanks for sharing your experimentation. Ant reason you didn't directly go for 3-D printing choosing whatever material you wanted the cover plates to be made of, since your volumes are few in number ? Another question I have is related to nickel allergies that harmonica players have faced using harmonicas from even well known manufacturers. Your opinion. Additionally do you know of Harmonica models that are certified by the manufacturer to be completely Nickel free ?

If you build a whisker-proof harmonica they will come. Do you mind if I share this on MBH?

They used to make watch cases with Argentium at the beginning of the 20th century... so it is not new in industry.

Well done and good results.
