Here is my problem. It isn't with any particular plane or specifically to any control horn. I have the same problem with each one. I must be sorta blind. I have followed instructions to the letter on several installs to this point, but always have the same problem. I drill my 1/16" hole in the mounting are only to find that when I reach the other side, I am a little bit off center. Not much, but enough that my eyes can't see the small angle that I am drilling. Would like to have a drill press, but do not. After I get the first screw attached it is a chore to get the other two in perfectly so they will screw into the nylon backplate. I am almost ready to enlarge the holes and bolt them on. Right now I am frustrated and will not finish the horns on my US60 till I figure out what I can do to keep this from happening.

Any tips to gettng the line up just right would be appreciated.
