Unfortunately, unless you do this for a living, one is unlikely to have
a nice temperature controlled iron with a micro-chisel tip, like a MetCal.
I've spent most of my adult life doing this and fine soldering without
ballsing things up is both an art and a skill, takes practise, a good
eye and a steady hand.
Buy an adaptor and use the Cat5 or 6 route, probably be a lot less headache.
