| Walter, it's probably much easier to build bellows than to explain in words how to build them, :>)
If you look carefully at the way your old bellows fold, you can build whatever bellows of that type. The geometry of the movement and of the flattened pattern is not so difficult to fathom, the manufacturing of the bellows is worse. I know, I was making bellows from one piece of material and succeeded. No cutting, no putting together of some parts, but it takes a lot of patience and the necessary knowledge. Instead of looking for verbal explanations look at the folds and you will get the understanding in an easier way. That's how I did it. My 2 cents. |
