I've decided to try and make new waterproof bellows for my Wire EDM machine. Details in this thread:
http://madmodder.net/index.php/topic,10085.0.htmlThey are very simple in that there are no complex end shapes, just a folded zig zag of material running vertically in channels above and below.
The bellows are 113 mm tall, each fold is 25 mm long so the channel they run in is 25 mm wide, and fully stretched they are about 600 mm long. The material is 0.6 mm thick and seems to be some sort of impregnated fabric.
In use they open and close very slowly but are subject to constant de-ionised water spray.
So what material to use and more importantly where to get it ?
(I thought I had some suitable replacements as mentioned in the other thread but they proved too narrow)
