rusted cable is out - now how to clear threads?
Short story: Now I have it so I can see the beginnings of threads, but the barrel's threads are still solidly stuck. Any suggestions on how to get the remnents of the barrel threads out? I don't have a 5mm tap on hand and I'm working it with a nail, but with no success...
Long story: After letting the corroded cable/barrel/rd soak, heating it, soaking it overnight, I still could not pull out the cable nor twist the barrel out.
I then filed the cable and barrel down on the flat side as suggested and carefully drilled out the cable. Initially, I couldn't drill straight down the center because the relatively hard steel cable kept making the tiny bit slip into the soft barrel. I tried drilling at a 45 degree angle into the center of the cable, hit a big pocket of rust, and the cable's filed end popped out. I then could drill all the way straight through. I drilled it out to the point where I can see threads appearing.
