Drilled out rivet pattern on upper skin at tip for Top Tip Angle (7V8-2). Marked a center line on Tip Angle flange, fitting so upper skin comes to the flat part just touching radius of angle.Then, I bent the Tip Angle to conform to upper skin curve & camber, using flutting pliers. Bending the Tip Angle until it's center line on the flange is centered in the rivet hole in the upper skin & proceeded on rivet hole at a time. Riveted tank cover in place, not riveting along rib # 1 until root is finished. Turned wing over & laid out cut for bottom skin at tip, a straight line from the rear channel to the spar tip. Finished laying out coordinates on nose. Filed all corners & edges and deburred all rivet holes.
