Long time no posts, a few things to catch up on. Since the last posting, Shelagh gave me a completed Sonex! This was my father’s day present made of tape, toothpicks, paper and pennies. It actually looks like a Sonex.
After the last post, I took apart the left wing. Before putting the left wing away, I got down the right wing spars from storage and drilled out the mounting holes. I was not happy with the 1/4” holes and had decided to drill the out to 5/16”. I was even less happy with those holes! I decided that I didn’t want to drill them out in the airplane, even with my piloted 3/8” reamer so I did it on the workbench. I am happy with the result, but I have departed from the suggested method. I am going to use a 3/8” centering bit when I attach the wings. This bit will ride in the drilled hole without cutting and drill through the spar tunnel, four simple holes and no updrilling. I think the result will be excellent. Here are four pictures of the drilled wings with the 3/8” attach bolts in place with a bunch of washers standing in for the spar tunnel material.
