The curved wire ball guide on the upper playfield, which simply sits in two holes, keeps working loose and popping out after hard hits, even after hot glue, matchstick-filled holes or super glue.
Upper playfield half-moon wire guide keeps popping out of its holes
Cause: The holes had worn oversize, and soft filler (matchstick wood) and brittle glues could not hold the guide's legs against the pounding.
Checks
- Pull the guide and check how loose its legs are in the holes and whether the wire is bent so tightly that it springs out.
Fix
- Plug the old holes with hardwood (toothpicks) and wood glue and let it set.
- Re-drill a step smaller than before, put a drop of epoxy (or an expanding glue) in each hole, and tap the guide's legs in so they fit tightly.
