Would think of re-using used safety-wire, would you. So, for the die-hard, maybe hose-clamps work until the installation is sorted out, then you go and buy the permanent clamp kit..... One question to the wiggins style: I saw them on the same helicopter brand/family, but the predecessor (AS350 - clamps, SA319B, Alouette III - wiggins). As I see it it would be rather hard to incorporate wiggins into a flexible hose system. THe older helo used mainly hardlines connected with wiggins. With swagged ends, yes - but now we are talking a rather pricey alternative. Might as well go with threaded-style ends - pricey too. Any wiggins idea?

A fire involving even a tiny amount of mercury produces a gas that can reduce your IQ to a dismal number in a few hours. Imagine 100 10 year olds with a 500 megaton capability.
