I need everyone's tips on how to form the sharp radius at the aft end of the F-1069 side skins. I can't seem to get a nice round bend when it gets to the point of twisting the skin with the aft vice grip and hitting the roll construction angles with a rubber mallet (29-11 step 5). Based on what is shown in the picture I've attached of one of my attempts, I'd say I'm probably hitting the construction angles too hard with the mallet which is causing the indentation in the skin but anything less doesn't seem to do anything. Also in that picture the bending block has slid a little bit but I can fix that with more clamps
The third picture is what my best attempt so far looks like when it is attached to the fuselage.
