Any ideas on sources for 4/40 pushrod material? That piano wire is too stiff, the hobby shops only sell pre threaded stock and its too small to cut threads. I need a good cheap source.

I made mine out of 3/32" 7071 Aluminum TIG welding wire. The alloy is pretty stiff, but being aluminum, it threads very easily and is very light weight.

Hope this helps...

Get your 4-40, and 5-40 dies from Microfasteners.com, they are cheaper and better quality than RodCkuk IMO.
