I have trouble with the switch operating mechanisms. I work in N-scale, and I had planned to use a mechanical manual throw for all my switches (motors are just more things that can break down over time), but the product I tried was based on a bent piano wire spring to hold the points in place. The problem is that the piano wire, which is intended to poke through the tie rod for its connection, is too wide; it is as wide as my N-scale tie rod. So that means that I have to find another way to connect it, and CA glue did not hold up over time (I'm back to pushing them loose with my finger). Soldering is a bad idea because 1. I cannot solder (I know this, I accept it) and 2. The points are already soldered to the tie rod and will loosen & shift. Aaargh! There has to be a way.
