Brief Description: More Rudder Dimpling and Countersinking
Today I finished dimpling all of the rudder parts. There is an aluminum wedge that runs the full length of the rudder training edge that fits between the rudder skins. The holes in the skins are dimpled so this wedge needs to have each hole countersunk to match the skin dimple (on each side of the wedge). I placed the angle on the edge of the drill press base and tilted the base until the wedge surface was level. I then proceeded to countersink all of those holes, flipped the wedge and repeated the process on the other side.
Next I placed the lead counterweight in the counterweight rib (guess that's why they named it the counterweight rib, huh?). Match drilled it to the rib and countersunk the lead weight so the flush head attachment screws would sit flush and I then dimpled the associated holes in the rib. That was about it for today. I thought I took a picture of the counter weight and rib but must've just thought I did. I'll take one tomorrow and update today's log.
The base of the drill press is set at an amgle to match the wedge
The drill press angle looks too steep but the level says it's right.
