Brief Description: Countersinked the trailing edge wedge
I was torn out the trailing edge wedge. The rule is that when you machine countersink something, that you don't countersink it so much that you make a sharp edge. Well, the trailing edge wedge is so thin that you almost can't help but do that when you countersink from both sides. I also had a problem with my microstop countersink tool wandering around and augering out the hole when the opposite side countersink and the near side countersinks would intersect and enlarge the hole. The hole guide on the counterskin tool was ineffective when the hole enlarged and the countersink die would wander around. So, I decided to secure the wedge in my drill press. I created a 12 degree wedge out of wood (approximately the angle of the wedge) and clamped the wedge under my drill press with my microstop tool mounted in the chuck. Did that on both sides and that seemed to work OK. Not spectacular, but OK. After the countersinking was done, I broke the sharp edges inside each hole with a rat tail file. Probably didn't need to since the holes end up being way oversized and will never touch the rivet, but I figure it's better safe than sorry. Since the countersink in the wedge engages with the dimple on the skin, the wedge shouldn't move around any once it is riveted. Now I think I'm ready to star assembling the rudder. Finally!
