F-UnitMad Posted April 5, 2015 Share Posted April 5, 2015 There are several suppliers of PTFE tube on Ebay, with various inside & outside diameters. Usually sold by the meter. I'd use tube of at least 1.5mm inside dia. for your wire. Link to post Share on other sites More sharing options...
RMweb Premium macgeordie Posted April 5, 2015 RMweb Premium Share Posted April 5, 2015 Hi Jim 1.25mm piano wire is pretty stiff stuff and won't bend very easily. If you only have fairly short runs from the switch on the edge of the layout to the point, you only need to stop the wire dropping down as it doesn't even need to be in a tube. For lengths up to about 18 inches I just used netting staples to hold the rod in place. You do need to stop it twisting but you can usually do that where the wire connects to the switch. you can join lengths and make the overall length adjustable by using the inserts in electrical terminal block by sliding the wire in from both sides so they overlap then then nip up the screws. For longer runs you might be better off with the plastic wire in tube products made for the model aircraft modellers for operating the rudder, elevators and ailerons etc. Ian Link to post Share on other sites More sharing options...

John Tomlinson Posted April 6, 2015 Share Posted April 6, 2015 MSE/ Wizard Models used to sell 5 metre rolls of nickel silver wire in a PTFE tube, for just the purpose you describe - you simply cut to length. The product reference was SM4 and it was £5 a pop. You could check their website, otherwise he does a lot of shows. John Link to post Share on other sites More sharing options...
hoovered Posted April 6, 2015 Share Posted April 6, 2015 Hi, you could try your local remote control model aircraft shop as they sell wire in plastic tubeing which is used on model aircraft to run from its servos to its control rudder/ alerons/etc. Link to post Share on other sites More sharing options...
