Today I did the other side of the horzontal stab to comply with SB00036. Experience kicked in as it took me 50% of the time it took yesterday ! After, I tried to put the stab on the aircraft tail. It fits perfectly.
I did an other thing that bothered me for a while. The skin over the last rib was wavy and looked a bit like a flower ! I unriveetted to top anoying part and redid it using some shims in some place to make the finish way better. I do not think it will be seen, but that was for my personal liking !
