I try to use magnetic tools whenever possible, but sometimes those nuts, bolts and screws slip from my fat fingers during repairs/mod installs and fall into playfield oblivion. Usually they turn up after searching, but when they don’t do you take everything apart until you find the lost doohickey or just let it lie (assuming you have extra hardware). I tend to just leave it if the game plays normally, but often wonder if there is a short or some other problem in my future. What do you think?

I love this tip. Thanks. Sounds like Zen and the Art of Pinball Maintenance.
