This evening I completed the control rod tunnel. Using the plans, Ifabricated the parts then drilled them out and clecoed. The hardest part of this step is lining up the mounting holes. (I lucked out and they ended up perfect.) The only part I did different from the plans was flush riveting the top piece. I read other builder logs about others who had done the same. I'm not sure that it makes any difference... but at least it will be smooth:-)
