    I've got some stripped screws under the playfield that are no longer able to hold up a coil assembly. There are 6 screws total.

    It's been recommend that I use the toothpick and glue method. Any additional advice would be welcome (such as type of glue, etc...).

    wood glue. I use bamboo skewers.

    Another method, although sometimes not possible due to location, is to use tnuts. Place tnuts into the hole or holes and allow the tnuts to be the hole for the screws. Personally, when the location of the screws allow this, I think its a better fix. The area got chewed up and enlarged the hole with the screw pprobably because of the amount of torque the screw gets. Tnuts will handle that much better than toothpicks and wood glue.

    +1. Done this many times and never had any issues.

    While I thin t-nuts would be the more elegant solution, I've had good luck with Tim Arnold's advice: http://tuukan.fliput.net/tim_en.html (See tip #24)
    Basically, put machine screws up through the holes and nut down onto them. I cover the ends with rubber tips. Voila!

    I too use Bamboo skewers with wood glue. Works great.

    Tee nuts are usually put on the bottom of the playfield to hold stuff on top, not stuff on the bottom of the playfield, there are a few acceptions. If I have some stripped holes on the bottom of a playfield, sometime I will upsize the thickness of the screw, not the length obviously, from #6 to #7 or 8. I have used #10 a few times but they require enlarging the holes in the item being mounted. Proximity to the edges of the playfield and cutouts is a concern, and I mark in pencil next to each enlagred hole so I know which size screw goes there .

    If you don't want to upsize, glue and boo works.'

    The other thing I've seen used pretty effectively is the cardboard shaft from a q-tip. A little thicker than a toothpick.

    I think I'll go with the bamboo skewers as they are thicker than a toothpick.

    Yup bamboo and wood glue . Add a little glue ,Stick the skewer into the hole and trim to fit . I also use a tooth pick to fill and tighten if it's really shot.

    +1 on the skewers. Much better sizing than toothpicks.

    I use skewers, toothpicks and two part epoxy cement.

    I have used three toothpicks in the past. It fits a lot better and it centers the screw.
