I need to make my own linkage rods. What type of material should be used? What are the originals made from? I am specifically looking at the Synergy rods, the diameter is 2.2 mm. I would like to get as close to this diameter as possible but need custom lengths.

Thanks,

jeff

I was hoping to buy some threaded rod that would work without having to buy more tools. or at least my wife would prefer I didn't buy anymore.

mcmaster-carr.com has some tool steel .085 or .088 rod in 36" lengths. You would have the use a die and thread the ends yourself. Rods are under $3 for a 36" length. They also have threaded rod, but I am unsure of thread pitch and size of stock N9 rods.

Du-Bro makes parts and linkage rods for what you are trying to do. Visit a local hobby shop that sells planes and you should find everything you need.

I used a Du Bro rod when i need a throttle linkage for my Synergy.

i dont know where i got this but i read it on some science forum somewhere that fully threaded rod is half as strong as rod threaded only at the ends ... just FYI

That's interesting, I plan on using carbon rod over the threaded rod for strength. It shouldn't be an issue.

That makes sense, because you take away half the material when you thread it.
