From: jonas at otter.se IIRC wire wrapping is supposed to be more reliable. I certainly remember that it is supposed to be easier to see whether a wrapped joint is good or bad than it is to see whether a soldered joint is good or bad. For a soldered joint to have maximum reliability, among other things the parts to be soldered must be solidly joined before soldering, and not held together by the solder. It is not hard to learn to wire wrap, certainly not with an electrical tool. You more or less just do it. I have never tried wrapping with an unpowered tool. I doubt that would be much more difficult, just harder on your hands. /Jonas
