Default Threading rod

I'm trying to locate wire that can be threaded for 8/32 hardware. Music wire is much too hard. I cannot use fully threaded rod for my required application.

I'm hoping someone can direct to me a source of such wire.

Thanks in advance for any help.

There is a site online, but I do not remember the link! They tell you how to soften the music wire and then how to harden it. I look a little harder, maybe someone out there will remember the site!!

Thanks. Yes I saw that on the Modelflyiing.com site. It references an article by Ray Vaillancourt on how to do that. It is probably a workable solution, but it is rather complicated and could result in brittle wire.

Someone on another thread suggested a welding supply store. I have been using 1/8 welding rod and cutting 6/32 threads in it, but I did not think to search for thicker rod. The 1/8 rod is available in most hardware stores, but I did not see thicker rod.

You wouldn't need to anneal the hold rod, just the area to be threaded.

I'll give it a shot. I've got the right size music wire.

AS long as it is just under push and pull stresses and not sheer you could for go the hardening!

http://vaillyaviation.com/images/Wor...re%20_web_.pdf This is the one I found and is probably the same as the one above. It did not work on my computer. After cutting, it does not really need to be hardened for most apps, but if it is, it can be gradually tempered after the quench. A straw colour, or almost blue depending on how hard or tough you want it.
