1971 Horn button assembly

[jlindquist]

I can't get my horn to work properly. The circuit is good and any time one of the 3 screws that holds the assembly to the column touches the horn button retainer, it properly activates the horn relay. However when I push the button it can't seem to make proper contact for it to work. Please take a look at the pictures and let me know if I am doing something wrong.
The horn contact disc with spring and silver contact point are new and installed correctly (so i think). after that the flying saucer disc is installed in a convex manner (high side facing driver) after that is the horn retaining ring then the pink insulator ring and lastly the 3 screws. What am I missing??
