Started working on the final construction of the tail cone this afternoon, what was supposed to be a few minutes in the workshop turned into two and a half hours!!
The plans call for you to construct the tail cone on two saw horse that are 38 inches high but I didn't want to build anything special to do this stage as space is limited so I gave my work benches a boost using the pop rivet boxes and pleased to report they worked a treat.
My skin bends for the lap joints seem OK, I've only had to rework a couple to make them better and I guess its easier to put more of a bend in than take it out. One thing I have had to do is prime some additional tail cone metal using a paint brush where skins overlap and I also used some of the JC5 jointing compound on one of the joints as I wanted to be sure it was a good joint between the panels.
I am hoping to fly tomorrow and if I don't I'll be in the workshop with rivet gun in hand. I've also noticed most of the skin holes will need a drill running through them as the primer has made the holes a little smaller than when it was bare metal and once again each rivet will be dipped into JC5 before setting - Overkill some might say but I feel it's a worthwhile step if a little messy thing to do.
