After a week away, I came back to the garage tonight. I drilled the first set of aileron pushrods, and deburred the ends. None of the rod ends needed sanding, they all fit easily into the ends of the tubes.
To my surprise, I found that the template Vans supplied for drilling the holes was not to scale. I made my own out of some graph paper. I also used an off it to practice drilling using my pipe clamp on the drill press. It all worked ok, so I moved onto the real parts.
Your pipe clamp looks impressive Neal
