I doubt that it would survive the procedure, I checked again and there were more weak spots and would-be tears than I first thought. These bellows are nothing but holes I am afraid. I am trying to source myself some compatible bellows somehow, I even wrote to Surplus Shed in a desperate attempt. Making my own would be the most desperate attempt because surprise-surprise, a lot of the stuff needed is only sold in bigger amounts that I will ever use up, making it quite costly and as someone said - there is nothing worse than making just one set of bellows.

If anyone reading this has a spare one around that will stretch to about 25cm/10 inches or so, please let me know, maybe we can arrange something.
