    I am doing a playfield swap on a Banzai Run and I broke a couple posts off screwing them into the new playfield. Can anyone recommend a good way to extract the broke post?

    Quoted from jhanley:

    Are you drilling a pilot hole before installing the stud?If not you need to.

    Yes this was my mistake. I need to drill out each hole to make them a little bigger. The copper type post studs are very weak and it doesn't take much to break them. It didn't take much tork at all.

    Quoted from MrArt2u:

    Ok, first I have to ask how hard are you torquing these things down to snap them? I see stress cracks in the clear around the ball guide screw too. Ease these in...
    That screw looks way too small to try to center drill and use a a standard extractor on.
    Now. What I would do. I’d buy a screw extractor from Rockler. It’s a pain in the arse to use but it drills *around* the broken screw. I use these when I can drill a new hole all the way through. I then use a post I can secure with a locknut underneath. Far more secure against angry pinballs.
    *extractor disclaimer. Much easier to use if you make a guide block to drill through and clamp it down to the playfield-examples of this are online- and these things are brittle. If you screw up and hit the metal screw, it will break some teeth. If you don’t have a Rockler nearby, order two.
    And note they have several sizes. Pick the one that works for you.

    Great suggestion, i just ordered one of these. It maybe the only way to go. They are not stress cracks you are seeing, just micro scratches in the clear.
