Holy thread revival.......but thanks to all who give excellent advice and guidance on what should be a simple task so that even idiots like me should be able to manage them.
Sadly, when designing something to be fool proof you should never underestimate the ingenuity of fools .... after wrestling with trying to get the little green beggar out for one and a half hours I decided it was time to put it all back together ready for work this morning.
Oh well, I'll try again next Tuesday when I have a few more hours of daylight to spare. Between then and now I just need to evolve longer yet thinner arms (ideally 4 of them) with a grip that is 5 times stronger. Eyes that can see around corners (even in the dark) and knees that bend the opposite way to make the position more comfortable whilst trying to perform the task. Shouldn't be too hard to achieve.
Thanks for listening!
