Started fitting the elevators on the Horizontal Stab with the help of my dad. Unfortunately, I didn't read ahead in the plans. I was only supposed to put one elevator on at a time so that I can drill the control horn. It is difficult to get the bolts on. Now, I need to take them off. We got the second elevator off, but now, I'll have to suffer through getting the first one off later. That's the price of education.
