Here's some photos of my custom made rig pole that is for sale, fully assembled it's 4.5m long and 5.6Kg and is made up of 3 sections:
1 - overall length 165cm, OD 37.8mm, wall thickness 3.4mm
2 - overall length 147.5cm, OD 50mm, wall thickness 3.5mm
3 - overall length 147.5cm, OD 50mm, wall thickness 3.5mm
it's very stiff and, I think, very light for an ally rig pole.
I am looking for £300 or near offer and collection from Milton Keynes or Abingdon, I can deliver it if you live somewhere in the MK16 to OX14 postcode area for a small charge.
I really don't want to post it unless I have to...
