Has anyone tried to use either gold or silver leaf to make AMT diaphragms? Just spray the trace pattern on the Mylar or plastic sheet and stick the leaf to it. I wonder if it would have continuity. It's definitely light and thin enough. Any ideas?
I tried silver leave once and there is no way of working with it, for amt you need thicker foil anyways so household foil could work depending on how big you make them. The thing is almost 30 procent of the pleatdepth is not covered with Alumnium.
So if you go so thin you might end up with a rather high impedance

yes it is used for planar allot, but go look at The Masking Shop - Helping You Mask For Less - Tapes and Discs - Silicone Tapes - Caps and Plugs for verry thin alumnium tape many people used it for all sorts of planars.
I have made ribbons for Decca ribbon tweeters using a thin aluminium foil that is found on a certain chocolate bar here in the UK. It's called a KitKat. Available everywhere in the UK.
I was told how to do it by a sound engineer who used to do it using the same method.
In recent years, most 'single bars' have had the foil replaced with a plastic sheet for health & safety reasons. But the multipacks have stayed wrapped in the same aluminium foil as there is an outer package as well.
The method I used to do the 'crinkly bits' was simple.
I needed a 50mm long x about 10mm wide foil after it had been corrugated.
I found that Fischer Price mechanical building sets (as often used in schools) had a long flat plastic gear track AND a plastic gear wheel to match. All I had to do was position the foil in between the two, press gently, and remove the corrugated foil. Then I flattened the ends.
Worked perfectly.
