Well, my first (left) flap turned out great - as I riveted the bottom skin along the spar I checked the angles of the flap brackets as I went. They started out true and stayed that way.
However, the right flap is another story. It started out true but after the first round of rivets (every 10th one) it was about 0.2 degrees out of true. I checked after each round of rivets and it ended up 0.5 degrees out of true.
It seems an odd way of checking for no twist - I deburred the aft edges of the flap hinge brackets as a pair - did I induce a half a degree difference?
If there was a half a degree out of true on one flap - is this a lot? I’m hoping not.
Once the trailing edges are done etc I can use a laser to check them but can’t think of a way at this stage that it would be helpful.
