Yes, I guess it´ll have to be something like that.
My first tests with the nail strips didn´t work out so well.
It is very hard to get the strips straight enough, it´ll be a sloppy membrane if any.

So I guess I´ll go hunting for some 2 - 2,5 times 6 - 7 mm bars tomorrow then.

My first attempt with nail strips didn´t work out so well.
They are impossible to get straight and are also too thin.
I need some sort of rod, capable of 170 degrees Celsius, 1-3 mm thick and 6-8 mm wide.
In case of 1 mm thick, I´d have to use 2 or 3 of them between each fold.

Any ideas on the material?

I got me some 2 mm x 15 mm aluminium bars.
The deepth of the pleats must be decided now before I make the acentric holes.

6, 7 or 8 mm in a 10 mm gap?

Pleece ask, it´s not a easy task to illustrate ideas.
