GrumpyMike, so in post #18, when a rail connects two components and you want to use the rest of the rail for something else, you strip off the copper? Is that what the greyed out square shapes are?
You make it look so easy. How thick is the tip of your iron? I measured mine at 1mm.
There is a tool for breaking the tracks, basically an 1/8 in drill in a handle.
f your bit is small it may not get heat in fast enough especially if its a long thin one.
