Soldering Leads to LEDS

    In the novel Catch 22 there is a character who likes boring and or tedious things because it makes his life seem longer. If that be true, I just added about ten years to mine. On my Oregon Railroad Supply mast signals I was trying to solder 36 AWG wire (after getting the insulation off) to 1.5V LEDS. I almost had it until the last lead and it broke off the LED, so nothing to show for my efforts. On the other hand, their dwarf signals were a snap. I need two mast signals, so by the time I get done I'll be about 22 years old again.

    Oh the humanity. Soldering is among my least favorite hobby chores.

    This signals are a real pain to assemble. I used magnet wire and with my old eyes and clunky fingers it took quite a long time. I feel your pain.

    For tiny connections and wire, I have found that the wire that electronic prototype circuit builders use to build experimental circuits, known as wire-wrap wire with Kynar insulation, works very well. The size I use is 0.019" in diameter including insulation; compared to #36 AWG decoder wire at 0.022". It can be bought in different colors of insulation. It also will can be bent to retain a shape to go around corners, etc.

    John, for those of us here in KC, Electronics Supply Company carries it in small spools for reasonable prices.

    John, it is possible to solder to the nub of a broken lead - I have had to do it at least once to save my own hide.
