Quoted from CaptainNeo:
BENT RAIL PROBLEM SOLVED::::::
Ok, you guys want to fix that rail issue. You know what they did on EM's and early solid state games, when they needed reinforcement, or sections where the ball would rest between rubber gap?
the answer is in the name of the machines we enjoy. Pinball.
Reason it's called pinball, is because nails were used as pins.
Put a nail in the playfield right in the middle of the guide rail and all your problems are solved. Doesn't have to be a big one. Just a thin support nail like you use on Xmas lights. Problem solved.
Is there a downside to adding an extra ball to the area to prevent the guide rail bending (and avoiding playfield modification)? Would the extra ball affect hits registering there?
