Is there a way to make bellows out of everyday material besides the pipe hairdryer way because all i have is galvanized steel pipe and that's a danger if it gets hot and emits Zn gas. Any ideas?

of course there are,  Look though this section and you will find many

first you would have to decide what kind of bellows you wanted to make.  I can think of at least 5 different types off the top of my head right now.  All of which can be made with scraps.  My first bellows was a box bellows made out of stuff I scrounged up for no money what so ever.  creativity is the key and understanding how the bellows you want to make works.
