crappy flare tool

well, I got them to flare, didnt split with the 45 anvil either. I annealed them and chamfered the end a tad with a burr. Im sure it will seal using a 45 inverted flare fitting. Im sure the tool would actually work as designed on softer metals, copper for sure. Next question: About how many inch/lbs are required to tighten these? I read it was finger snug, then wrench until it "snugs down" then 1/6 more turn, does this sound accurate? I have almost broken brake fittings trying to loosen them so I guess they can take alot of torque.
