Brief Description: Deburred Match Drilled Holes, Countersunk R-1006
Took all the clecos out of the rudder and deburred all of the match drilled holes. Used a single flute 100 degree hex shank deburring tool (DB04) in a Ryobi cordless screw driver as well as a hand deburring tool (BAT-196HDT).
Also used a Cleaveland Tool drill jig (DJ25) to countersink the R-1006 trailing edge. When I countersunk the second side the match drilled #40 holes got a little larger but I understand this to be normal. There is no way to properly countersink the TE without this happening.
