Soldering a clevis on the unthreaded end is one way, you can also thread it, bend a ninety degree in it, etc.

Personally I will solder mine and use ball links if the application will allow them. (Control surfaces and some engine installations). Ball links help maintain mechanical advantage and all but eliminate binding. If the part you are soldering too is threaded then you can adjust the link without removing either end but you will need lock nuts on both ends up against the connector to hold the rod tight so it doesn't loosen during vibration and flight.

Threading is also the other way I do it. Same benefits and requirements as above but without the chance of the solder joint breaking, unless you can really "sweat" a good solder joint. I prefer threading on high stress surfaces and solder on low stress as in the throttle.

Some others may have a better way but this is how I do it and it has worked well for me.

Where do you fly in Lancaster. I live in between Hershey and Elizabethtown so I am not far from you?
