Hi i want to make light strong tent pole in 2 or 3 parts socketed together. The pole needs to be 1200mm long. I know a cf walking pole I have about 13mm od about 1mm wall 3 parts with aluminium spigots 130 gram weight, is strong enough and a 9mm easton 3 part Al alloy about .5mm wall, 74 gram weight, is a bit too springy. So i thought your 12.7 wrapped id cf tube would be about right. Is your woven tube anystronger for the weight than your wrapped? I want the spigot to be a close sliding fit and not to be the point of failure. Would you think aluminium or do you make a standard wrapped tube or wrapped or pultruded rod that would work?

I like the outside joiner idea . If i got 12-10 woven at 53 gram per m joined outside by 12.7-15.5 x 50mm long weight 4.5 g plus epoxy i might get a total weight of 70 gram. 0.7mm is a bit slack for a sliding fit i would guess 0.5mm would be about right, but i think it will do. My 13-11 ish hiking pole is stronger than needed i feel. I guess the 12-10 pole will be the same weight but stiffer than the 9mm easton Al tube that is a bit too springy.
