Help!
Buy piano or music wire for pushrods from Malta

Hello to all,
I am new to this hobby and i am trying to get the best of it.
I am doing a scratchbuild and i need piano/music wire for pushrods.
I live in Malta and here all is more expansive and hard to get.

I was wondering if someone know a place from where i can buy some preferably local but if not somewhere with low shipping cost.

Size: 0.047"/1.2mm width by 36"/1m length
Example: http://www.3dxhobbies.com/music-wire...36-music-wire/

Regards,

Andrew

Sorry can't help on the piano wire, but what about alternative methods.

For a long(ish) push rod I use hard balsa strip, (often 1/4" sq), with sort wire ends. You may get away with a slightly softer wire for short rods such as the larger size paper clip.
It can depend on the expected load on the push rod.

Another method is the 'pull-pull', where you use a wire, (something like a fishing trace), connected between the servo, (double arm), and two control horns.

There are probably other methods that don't use piano wire, or the pre-threaded push rod for a quick-link.

Innovation is one of the mind stretchers for model builders.


Addition: Just thought there are also the 'plastic snakes', but they do require the end fittings.

Some have used brazing or welding rod for push rods. It would be a good idea to look for some tube to put it in too.

Another useful source of metal rods is bicycle wheel spokes. Look for the thinner ones for weight saving. You may even find some clevises will screw on the threaded end, or even use the 90deg bend with the 'knob' end at the horn or servo arm.

Those little flags used to mark buried power lines or mark wireless dog fences are 1.6mm. Also Suspended ceiling wire is aluminum and about the same 1.6mm.
