Reply To: Gem Mercontrol PTFE tube

[Ray BydeParticipant]

Have you tried using thick walled, small bore copper tubing instead of the PTFE tube? This is what used to be supplied with Mercontrol point control system. I’m not 100% surre if this is still available as I bought mine several years ago, but I have used it with 0.5 mm piano wire and it works quite well. As long as the wire is passed through the copper tube before you try to curve it, it will go round quite tight curves.
