clecoed on skins. match drilled skins to skeleton.
bit of confusion here. plans say to final drill the piloted holes, then debur, then dimple. on some practice sheet, this method makes the rivet very loose in the hole.
ref books say to pilot drill, then debur, then dimple, then final drill.
appears best to do this, only not to final drill. the dimpling makes a plenty big enough hole.
think i''ll check ac43.13 and with tech counselor on proper technique.
