Using the V-shape block in the drill press, I began to drill the inserts in the push tubes. First I started off with #40 pilot holes, then I upsized the, to #30 holes.
Next I cut the steel aileron tubes to size.
Again, I used autocad to draw a template of where the holes needed to go and taped the template onto the rod.
It was now time to prime the insides of the tubes. I fastened a piece of scotch bright to a dowel and inserted it into the drill. This polished and cleaned the inside of the tubes.
Once cleaned and ready. I taped all the holes and dumped wet primer in the tubes. I rolled them around a bit and then dumped the excess out. Next I wanted to get the inserts in the tubes before the primer dried. I used a gun and bar to set the steel tubes.
