Mr. Pinball Tip:

On a Chicago Coin SOUND STAGE I recently bought, all the plungers in the stepper units were rusted and thus none of the stepper units (three of them with about seven plungers in all) would function.

The solution I found that worked for me was to remove each plunger. Next, using a circular wire brush mounted on a drill (about US$3 from my hardware store) and holding the plunger with strong pliers, the rust came off. Apply pressure as needed. To smooth, I then used 1200 grit sandpaper to lightly sand each plunger. The 1200 grit also was great to lightly sand the metal coil sleeves the plungers fitted into.

SAFETY FIRST! ALWAYS WEAR EYE PROTECTION AND GLOVES. THE PLUNGER CAN EASILY FLY OUT OF THE PLIERS IF YOUR GRIP ISN'T STRONG ENOUGH AND DAMAGE YOUR EYES. THE WIRE BRUSH WILL GRAZE YOU BADLY SHOULD YOU MAKE CONTACT WITH YOUR SKIN.
