Just keep Playin...!!
Here's how I would fix it
1 of 2 ways
#1 unscrew the shooter assy and file/grind the shooter rod *outside* the game - keeps shavings out of the game
#2 pull the shooter, clamp it in the 'pulled' position, and cut the knob off the shooter then carefully release the clamp
Either of these ways, you don't get a cabinet full of shavings
