I spent time today deburring rudder parts, fluting ribs, radiusing leading edges of ribs, reading plans, and some other tasks such as drilling out a couple of holes in the rudder skins. I realized I needed a few more tools, including a pop rivet dimple die with 120 degree head (vs 100 degree for solid rivets). I ordered the new parts from Cleveland Aircraft tools, as they have been super helpful in the past (as have all other companies I’ve worked with so far), and also picked up some 3M tape for the trailing edge.
