Nice one Tosh I think that may be the problem 
Thanks
No problem. It's nice to answer a question, rather than ask one for a change! 
Geee Tosh.
Over the years you have answered far more questions than you have asked with your new van mount. You are still well in 'credit'. As you rightly have said, once you've got to understand your system intimately then you can solve your own problems as they raise their heads - it's a good learning curve.
I remember how 'complicated' the fishing pole conversion seemed to me, until you organised a step by step process which we did. Using those poles was a stepping stone into the carbon fibre world which weaned me off the Unger Teleplus poles which I thought were the most brilliant poles ever.
I for one will be forever grateful for your explanation of things and how you patiently answered all of questions we threw at you - yes in our ignorance we made the project far more complicated than it was.
Although we now use Gardiner poles, the fishing pole I converted is still part of my toolbox and find it great for gutter and fascia cleans as it's so light and rigid.
My wife uses the last section and a half as a light downstair pole.
Thanks for all you have given us over the years.
