Output gear with screw
Adding a #4 machine screw to the output gear is a good idea if the load on the servo could strip the plastic threads of the output gear.
To put this screw in place I had to drill out the output gear twice. First I drilled right through to allow the screw to fit. Then I drilled the bottom a bit wider to accomodate the screw head. Be careful not to drill farther than necessary with this latter operation.
There's really nothing holding the screw in place at this point but it doesn't slip easily either.
