There's no way to avoid shorting adjacent turns. Else, there would be
gaps in the output voltage! However, the width could be important
to avoid shorting more than one adjacent turn.

ISTR some specification for resistivity for that purpose but these days you
have to use what you can get.

I once saw an ad for someone who was promoting the idea of a bifilar
wound variable autotransformer which was meant to "cure" this problem.
Personally, it didn't seem to be much of a solution, and I've never
seen them on the market. It sounds like an idea which was too hastily
presented, and it must have died as soon as someone thought more
seriously about it.

Anyone else remember seeing this?
