I use a Sullivan 4-40 Brass Solder End, from the solder end, drill into the brass end with a .040" drill about 3/8" deep, cut off the female sleeve and dress the end, solder 1/32" cable into the 4-40 thread piece and use Dubro 4-40 rod ends. I use Sullivan 4-40 nuts for jamming, they are 3/16" hex size.
