The cores from ordinary mains twin and earth are quite suitable - stiff enough but pliable enough to make fine adjustments after installation.

Green Street now at which you would have found from the Scalefour links page. Keith

Piano wire.

Get it from your nearest Model Aircraft shop.

you could befriend a violinist and cadge used e-strings

Guitar strings also - but they are steel and will rust - brass piano wire is better (some model shops sell them in roughly 1m lengths) For hand operation I picked up some bowden cable from a R/C model shop and used a short length of piano wire for the last inch or so (the bowden inner I had was a bit too big and visible).

No applicable to power operation but you can use a pull system with fishing line. I did this once on a garden layout to control the remote return loop points, with loops on the pulling ends to which a weight was hung to remind me what line was currently pulled. The run was several yards and I was not able to get any version of wire-in-tube to work (including lengths of coathanger wire joined with chock block and run in screw eyes).

Many thanks for the new link.

With a return spring it can be power operated on the pull stroke.

Can't you get it in longer lengths in piano shops?

Air-in-tube works a dream.

Many thanks to all who replied. I will try and get hold of some piano wire at the local model shop, or failing that, the local music shop ;-)

Any ideas as to what would be the best gauge? C flat or B sharp? ;-)

Ian,

Last time I bought guitar strings they were ranged in diameters in thous of inches, so your going to have to equate keys to thous - have fun :-)

Jim.

Bump!

Hi all,

Just wondering if anyone can advise me on the best thickness of piano wire to use for turnout operation off of tortoise/fulgurex motors? I've read

TIA,

Ian J.
