We drill two 1/2" holes in the bottom of the rudder and put the screws in
with lock tight.   My Standard Aviation Maintaince Handbook is very clear
that all bolts are to be facing down or back.   I'm breaking that rule with
my removable rudder horn installation.  If you leave the bottom of the
rudder open nobody will see it, it will not slow your plane down and you can
wire the horns on with bolts the way it should be.

Don't over do it....thats why we have three hinges.If you want to do it
better use nut plates on your aileron and rudder hinges.  I wouldn't do it
any other way.

Just don't over or under crimp your nico sleeves they are fine.  Besides in
the rare event that you might need to land without rudders, its really not
hard, just sloppy.
