Keep your hands clear of things like thumper bumpers and ball return chutes. They can generate enough force to break fingers. Ask me how I know this ;-( Remember when you have to top glass off and the power on, that those electromechanical devices are intended to propel a ball weighing several ounces at high speeds across the table. Take care.
If you were closer, I'd volunteer to help you work on it, just so I could play it.
