I know that I can buy a replacement bellows, but I would rather make a replacement one. Possibly out of leather. I do not wish to take my working one apart to see whats inside.
Here is a link to one. http://www.dave-cushman.net/bee/gif/tool/smokexsect.gif
Is there usually only 1 hole at the bottom ? Is there a 'one way flap'/valve ? If there is no valve does air just exit the bottom hole when the bellows is compressed and the spring inside the bellows makes the air flow reverse in the same hole to reinflate the bellows.
I understand it's not rocket science, but I do not want to disassemble my working one, but I do want a homemade/working spare.
