Paul, Thanks for the offer.
It is all time now, I have started to make my own adjustable pole.
All the other bits I need have been made or are nearly completed.
I'll keep my eyes open and if something local appears then I could always scrap my home made.

Worked all day Saturday on the thing then at 19:15 urgent call out for a 21:00 Manchester to Stansted Airports. $ x cabin crew ladies and one co-pilot. Lovely bunch. Good journey apart from an accident northbound just past Keele services. Home for 04:30. Had a cuppa and hit the bed in the half finished bedroom.
Up at 09:00and finally finished for 23:00. Knackered.
Looking at it now I can only say, "Yep it looks good".
SWMBO is smiling.
