[Boatanchors] Speaker repair

[Glen Zook]

Fact that the silkspan shrinks is the problem.  It works great for model airplanes (in my younger days I built quite a few), but the very fact that it does shrink when "dope" is applied could definitely cause physical distortion to the speaker cone.  Then, the physical distortion could cause distortion in the reproduced sound from the speaker.

Using a paper that doesn't shrink is, in my experience, a much better solution.

Once doped, I doubt water would do much. Planes I built with it are intact
after over 50 years.
