I just bought a Walthers Shinohara #6 double crossover and I am about to install it.
I noticed when I looked at the underside of the double crossover that one of the metal jumpers was loose on one side and not making contact with the bottom of the rail.
Which fix would you recommend? Solder the jumper or just use hot glue to hold the jumper against the rail? I am a little reluctant to solder because of the small spot involved and the possibility of melting the surround plastic.
Soldering is the only way to insure electrical continuity. Hot melt glue is an insulator, so you can’t use it. There are some liquid solder products available that require no heat.
I had hoped to simply hold down the jumper in contact with the rail by the pressure of the hot glue sitting on top of the jumper. But, I suppose the risk is that the hot glue will seep between the jumper and the rail, effectively insulating the spot, exactly the opposite of what I want.
