Darrol Cady can supply the push rods for our planes. These rods are 24" long, about 4mm in diameter and cost $5.00. They are hollow and can be threaded to accept a 440-threaded rod. The weight is 20% that of a normal 440 threaded rod.

A typical setup might be to cut the C/F rod to the length you want using a Drumel tool to cut the C/F and slip a ½" long aluminum sleeve over the end securing it with a drop of medium CA. Your hobby shop should carry K&S tubes and they make a nice aluminum tube that just fits over the CF rod.. The aluminum tube is to stop the C/F rod from splitting under side load. Cut two lengths of 440 threaded stock about 1" long. Use a tap to cut threads into the ½" CF rod.

Now put epoxy on the 440 thread and screw in the 440 rod half an inch into the C/F rod. You should now have a C/F push rod with 440 ends that is very light in weight and very rigid.
