Hi David,
I think it’s worth trying – it’s one of those things I’ve been meaning to try for ages but haven’t got around to, myself. What I’m not sure about is the longevity of a glued joint on the inside of the tube fabric, and what’s the best adhesive to use. Some people have reported that a glue called HH-66 works well, but I can’t find it where I live.
If you give this a try, please let us know how it goes!
