Aileron Tip Rib

Aileron Rib 1 – Trace and cut out blank 2 – Drill hole for radius before notching 3 – Trim notch and then file edges to side. 4 – Form angles Aileron Skin 1 – Trim longest cut edge to exact size. 2 – Clean up front edge (shortest edge) 3 – File angle at trailing edge to match tip rib. 4 – Trim the lower edge of the aileron skin to meet the front and back. Clean up the edges and check the fit of the tip rib. After completing the tip rib and aileron skin I started to layout the rivet holes. I started do drill the holes for the counterbalance ribs but I discovered that I need a long drill bit.
