OK I need some serious help here and I need it from someone who is into extreme detailing. Now I've been doing this all my life but recently started getting down to the work's of things in detailing. OK here's what I am attempting. I am putting brake line's on all of my car's and loco's but! (here's the tricky part) i am trying to find a tubing that is scale brake line size b/c extreamly flexable and i mean "extreamly" flexable. reason for this is b/c i was just throwing some thing together to get the idea of how to make it work to where the brake lines between to cars will hook up for a more detail and realistic look. i used 2 type's of thread and magnet's out of an old hard drive. reason why i used an old harddrive for the magents is b/c they are very powerful. then i took them and busted them up into many piece's where i later crunched in a pair of plier's to make small magnetic grandulets. (sorry if i can't spell!) but i took 2 piece's of the grounded up magnet and glued each one on it's own piece of string and temporaraly glued it to the side of two car's. the result's were great. you coould couple the car's without them hooking up and leave them for a switching type look or use a piece of brass rod bent on one end to pull them together and they connect and they even stay together runing around on tight curve's. but what i need is to find a tubing that is just about as flexable os thread is but will be to scale in HO. can anyone help me? :NOTE: my email has changed and i havent gotten a chance to to do so here yet so it is: xcrash42069x@wmconnect.com thanx
