Ball Link Help
I am trying to install this ball link onto the 4-40 rod (threaded rod) and am having difficulty. The inside of the link is heavy nylon without any threads and to install the rod, you need to cut threads into the nylon as you put it on the rod. However, in the one that I did, the nylon is soft enough that when i was done the link itself was pretty roughed up. Sort of like trying to put bolts on with pliers rather than sockets. If the end was hexagon or similar, I could put a small open end wrench on it and it would stay pretty clean. However, it is round except for a couple of small protrusions on the side...which by the time I had attached the link, were completely gone. I also tried rubbing a bar of soap on the threads hoping to have the link go on easier. It worked somewhat, but not well enough.
Is there a tool that I should be using, or a different process? I am reluctant to try another until I have a better way...these things are not cheap.[ATTACH=CONFIG]1934002[/ATTACH]
