Hi,

I'm new to carbon fibre but looking to use it for a new project(s).
1) I am aiming to use 25mmOD tube (either 1mm or 1.5mm wall thickness) and end up with a pole just short of 2.5m long
2) The pole will be carried horizontally at thigh height
3) A shoulder strap will be attached to the pole at one quarter and three quarters of the way along the length
4) On each end of the pole will be a 2kg weight

What are your thoughts about flexibility?
Is the proposed 25mmOD tube a sensible size for the length and weights attached?
Given the above, what about wall thickness?
I'm not looking exact engineering figures - just want to know if this will be fairly rigid or would I need to increase the diameter?

My next problem is that I need the pole to be able to break down into 0.5m lengths
Thoughts are along the lines of gluing a protruding insert into one end of each pole - so you end up with male and female ends that can push into each other and butt up
Now I need a quick release type connector (permanently attached at one end of each pole) to stop the tubes moving apart while in use. I can find lots on-line but they are all for telescopic tubes so mate with two different diameter tubes. They also need to be plastic or aluminium (I can replace steel bolts and pins with brass). Anybody come across such a thing? Or indeed have any ideas about quickly, securely and temporarily joining tubes of the same diameter?
(it was my intension to a key-way lug at each joint to avoid rotation)
