    Default "Piano” Wire and Tubing Size

    I have to run my manual switch throws across several tracks in order to mount them. I am using Atlas Code 55 switches and Caboose throws. The tracks are not yet glued down so I will be cutting a groove in the cork under the track to accommodate the tubing. What size “piano” wire and tubing do you use to connect the switch and throw? Thank you.

    try these . there for rc planes and they work great are very flexable . they can be run any where pretty much. come in many lengths and can be cut where ever you want them to end at.

    Sid, thank you for the reply. Unfortunately in order to attach the throw to the switch track, I need a thin wire that I can bend and thread into the small switch track eyelet.

    FrankieD the plastic tube that runs in the center comes with a small threaded insert to except a clevis hook, this can be used as is or replaced with a small piece of music wire.

    Yellow rod slides inside red tube . You can fabricate any connector you would like and glue into hollow yellow rod. very flexible connector. These are used to snake manual connections in model airplane wings and fuse.

    @FrankieD, figure out the I.D. (inside diameter) of the RC tubing you'll be using and find steel wire to match, either at the LHS or hardware store.

    Slide the wire into the tube, bend an small "L" at the end that goes to the the switch throw rod and finagle it into the hole in the throw rod. Trim the excess with wire cutters.

    Trim the other end to fit with your CI throws.

    in the rc hobby shops you look for the plastic push rods then hunt down the long wire that has threads on the ends for screwing those into the plastic rods or you can just CA them in there. basically you can make or bend any co configuration you want too. you could also use some drip tubing with a flexible cable but you would have to put that real close to what ever you making move because it bends very easy. but that rc push rod stuff is pretty good and way over kill for strength .

    this pic should give an idea how it works. you will have to fine tune you wire end to go through the turn control ie grind the ends down or ?

    you could probaly drill a small hole right through the end of the plastic inner tube and insert a very small wire right through that to connect to the control on the turn out just be sure to use CA glue or ? to secure it. also dont froget you can use reg sewing thread and tie the ends like a fishing fly, then ca the thread so it dont unravel.

    For controlling Atlas N-scale Code 55 turnouts, I use 0.032 inch music (piano) wire inside 1/16-inch brass tubing. Standard 1/16-inch brass tubing has an inside diameter of 0.035, so 0.032 music wire fits nicely. The hole in the Atlas turnout's throw bar is just the right size for the 0.032 inch music wire.

    This solution assumes you can need a straight linkage.

    Jeff, that is exactly what i was asking and am doing. Thank you. I spent a good chunk of time in a craft store playing with the sizes to get them right, and yup, those were the sizes I bought.
