AGHRMatt posted:I would give the Atlas joiners a slight squeeze with pliers to tighten them up against the Ross/Gargraves track. As for the Atlas-style power drops, You can grind the bottom of a regular Atlas joiner and solder a wire to it (16-18 gauge) and they'll work fine. I'd apply conductive grease to the rails before installing the joiners to prevent oxidation from building up in the joint.
I did mention in my original post that I could probably make them a lot cheaper than buying them, and easier than soldering to the track.
More curious about the effectiveness compared to soldering direct, since there are other connectors in a run of track anyway.
