Rudder Trailing Edge

I haven't been able to do much more on the rudder or elevators until I get the new 4" yoke.  That has me twiddling my thumbs a little bit, but now that I have everything primed, I went back to finishing the rudder.  The last piece (aside from finishing the rivets I need the yoke for) is to do the trailing edge.  I countersunk the holes in the wedge that goes in between the skins at the trailing edge.  Doing this by hand is known to be problematic because the material is thin enough that when you do the second side the hole enlarges and the countersink flute wanders.  Dad and I had set up the drill press before he left, angling it so that the cage matched the angle of the wedge.  This worked great.  It was very easy to countersink the wedge.


It's too late to get any additional work done tonight, but as I'm writing this, the UPS man brought my new yoke.  This is a 4" throat, whereas my biggest throat up to this point was 3".  It also does not accept a die on the upper nose.  It is solid, meaning you can squeeze rivets right up against the nose, allowing squeezing in tighter spaces.
