Pushrods

There are two sets of aileron pushrods required (long and short).  The short ones are powder-coated steel, while the longer ones are aluminum tubing.  Both of them have you rivet a threaded insert into the end.  After cutting both to length, you can prime the inside by pouring a diluted mixture of primer into the end of the tubes, then taping over both ends.  You can roll it around to allow the primer to soak all internal tube surface area.  Doesn't work the best, but it is better than nothing.

When determining where to place the rivets, be sure to mark the full inserted position of the insert (blue line) to ensure that the rivet is through both surfaces.  While making the shorter pushrods, it is extremely difficult to keep from clinching rivets.  The easiest way to rivet these by far is to use the c-frame tool:

When making the longer pushrods, the builder must evenly space several rivets around the circumference of the pushrod.  A piece of tape equal to the circumference of the pushrod can be used to mark even spaces.  It then can be wrapped around the pushrod to identify the locations to drill:

You will see in the right picture that two wood blocks were used to hold the pushrod in place while drilling in the drill press.  Several people purchase a v-block for centering the pushrod while drilling, but it did not seem necessary to me.
