Another approach to stripping magnet wire is to lightly burn the end of the wire with a match or lighter -- don't cook it to a crisp, just enough to burn the insulation. Then remove the insulation by laying the wire on a flat surface and rubbing it with a pencil eraser. With a little practice, you can wind up with very clean copper on the end of the wire. Another problem with very fine wire is that the copper disolves into the solder used to tin it, resulting in wire that is much thinner than it's supposed to be after tinning (or non-existant). This is especially true with the high temperatures needed to remove insulation such as Beldsol and the like. The answer to this is a special solder with lower copper solubility.
