Anybody here happen to know what alloy is used in these adjustable crutches?
I should have some time over the next 5 weeks to do so real sewing and I am thinking about strong tarp poles
25mm OD stuff with ~1mm wall thickness
While similar in look to the centre poles that came with my Megamids I'm not sure what alloy those are either or for that matter my Bulldog pole sets.
Because the deflection is greatest in the centre of a rod or tube I'd use these in the middle of the pole set rather than aim for minimum packing bulk
Using with the Easton .742 poles because experience tells me anything less simply isn't strong enough in the Alps
