Havent had a chance to work on plane lately. I have been on call at work which doesnt provide much free time. Now that I am off of call, its time to get back to the plane. Riveted the HS-411PP together using the rivet callout in the plans. From what I have seen from other builders is that they use a different length rivet to get a better shop head. The rivet callout came out pretty close but a little undersized according to the rivet gauge. Some people have said its ok. Since the horizontal rear spar is completely drilled, I took everything and deburred the pieces. No pictures of that because that is the most enjoyable part??
