Are there any updates or pictures of this procedure? I just finished installing lower rudder skins and a new bellcrank. I am now 10 OZ underweigh at 27 inches and will have to open the horn to install the weight. I think this might loosen the factory installed 4 lb weight. Any ideas would be grateful.

Help, how do you add weight to the rudder horn? What is the best procedure? I installed new lower skins and i'm 10 oz short of balance.
