Regular listeners will be aware of one of two little tube problems I have had over the last few months
and probably think
(sorry - if its any consolation I am a lot more bored with it than you....!)
Another interesting possibility has presented itself so I thought I would share the idea in case it is useful to anybody
A guy here had a similar problem a few years ago with a Tornado rib and I was talking to him this morning. I had been told he bought inner tubes but apparently not. The idea he came up with was to get a new "proper" tube section made up the same length as the aft chamber with a blank end on one end and a normal tube cone end on the other.
Humber made it for him out of hypalon just as you would make a normal tube, then he cut the end off the old tube, slid the new "hypalon sausage" up inside the remains of the old tube, inflated it and it was held fast by the air pressure, the overlapping edge of course is a trailing edge so no problems with the water flow, simple but brilliant
He said he could have glued around the trailing edge (and that was the original idea) to secure the sausage inside the old tube but he never got around to it as it never moved. The inflation valve was built in to the end cone when the sausage was made, so he basically never had to do any tube gluing at all just chop the end off the old tube, stuff the sausage in and blow it up, 5 minute repair.
There seems to be another benefit which is that the aft chamber is now basically double thickness so any damage to the outer layer of hypalon (the original tube) will have more or less no effect at all on the new inner part - so it adds a full sized wear patch in effect
There is still a light at the end of the tunnel if my ham fisted attempts at gluing fail
he said it cost a few hundred quid to have the sections made but is pretty much guaranteed to solve the problem.
Just wish I had spoken to him a month or two ago and I could have had the bits here by now
