I'm having issues with wiring a layout for me and my son, specifically soldering. I've read some articles where it recommends a track bus and droppers soldered to the track at intervals so that's what I've done. As well as being better generally,
it's also because I've had issues with older engines shorting out on certain points and I've got some insulated joiners. Anyway, I've also read that mains electric cable is good for the track bus which I thought was useful as I had some spare. I stripped out
the earth (i.e. bare) wire and did a loop under the baseboard.
I had real problems soldering the droppers to new track pieces. I've got 3 versions of track - older pieces made in England, some in Austria(!) and new pieces from China. I can solder easily
to the older bits, but cannot solder to the new bits. I've tried fishplates and the underside of the rails with no luck, solder just rolls off. I managed to get round that, sometimes by swapping fishplates from older pieces onto new ones and managed to finish
all the droppers. The easy bit I thought was then to solder to the bare copper earth cable, but I can't solder to that either. I would have though solder (the electrical stuff) would have happily stuck to copper, but again just rolls off. I've scrubbed some
areas with emery paper, but to no avail.
Any ideas? I've spent all weekend doing this and I'm mightily cheased off that it's still not finished. Grrrr.
