I see no harm in pinning a CA hinge the same way. As for using steel for pinning the hinge, DON'T. CA does not bond to metal as well as wood because metal is non-porous. CA does bond quite well to covering material.

I think excap232's timing was to do one side of the hinge in both surfaces at the same time, wait several minutes to ensure it has fully set, then flip it over and do the other side. Make sure you apply enough the first time (per side) since you shouldn't re-apply glue to a side which has already been glued. Using thin CA, it will wick to the ends (but not around the corner to the other side) untill full, then it will start to puddle in the middle where you are applying it. That's when you stop. It's been a few years, but I think it will take approx 5-10 drops per side.
