I have the Peco turntable, which is adequate to my needs, but bringing the rails to the bridge is proving not wholly intuitive. The plastic thingies they supply are alright in their way, but appear to require the filing of a slot in the rail foot (not an issue, but is that right?). Also the rails will curve as they lead away, putting sideways force on this part of the assembly. Should I pin through the base and solder in some rail joiners instead? Or am I worrying about nothing?
