[Graham G3ZVT]

I co-built a Wimshurst machine with a school friend circa 1966.
It was a design from a book, and used a pair of 12 inch 78's.
The design included a home made condenser using paper and tinfoil cut to a template, and

I remember "dope thinners" was required.

I'd quite like to find a copy of that book, or article.
