I purchased several 2-56 size control rods to set up the control throws on an airplane. I also bought a 2-56 die to thread 2-56 rods to make the aeliron control rods with. Using the die without a handle, I was able to cut the thread on one of the 2-56 rods. Then I tried to screw a 2-56 clevis onto the newly threaded rod only to discover that the clevis just slid on the rod without screwing on. What am I missing? What size of rod should I use to cut a 2-56 thread? What is the real size of a 2-56 clevis? What is the real size of the rod?
