My fingers are so sore from deburring I can barely type this entry! :)
That's only partially true, but I did spend several hours with a file, deburring blade, and scotch brite pad deburring the edges on all of the pieces I have been working on (14 stiffeners, 7 shear clips, 2 ribs, 2 attach strips, a shim and a rudder horn brace). I am very happy with the way the pieces for the internal structure of the rudder turned out!
I also cleco'd several rudder pieces to the rudder spar in preparation for final drilling (and more deburring).
