Hi, I'm doing now the tricky job of building an asymmetric, tapered bellow.
I'm wondering right now if anyone of you has experience in building bellows.
I would love to have some answers to my material questions:
- do you use leather-cardboard-cotton or cotton-cardboard-cotton?
- I found a cotton/polyester mix in black, very thin, not vulcanized, but appearently totally lighttight. Any opinions on that?
- is an outer layer in leather highly recommended?
- glues: leather-carboard? Sparyglue? Vynil glue? Bookbinder glue? Any ideas?
cartboard-cotton? Same questions...
Thank's for any comment on that!
It was big fun to derive the mathematical and geometrical issues of the bellow....
