My magneto horn diaphragm has rust holes and does not function. Where can I obtain a replacement? It must have the threaded center for the sound adjustment device.
I bought mine at Fun projects. John did make the diaphragm that he offer fit the magneto horn.
I just needed to build the threaded center part in the hole he made in the center of the diaphragm.
I will try to find some photos of the rebuild and come back.
I had some trouble to fined it but here is it all.
The two fellows on one of the pictures is the crew that helped to make it buzz again.
