    What is the best way to remove broken screws from the playfield. I have 2 that are below the surface that I need to extract. I thought I would get opinions before I completely mess up the playfield.

    Below the surface? ouch.. I have only done a couple that where flush or a little above. Diagonal cutters or electronic cutters work great if you can grip it. Or with Dremel and cutting wheel make a slot for a small screw driver. Below I got nothing. Did you try you tube searching? maybe worth a shot.
    Only other thing I can think of is maybe a screw extractor bit or a small similar size screw and epoxy.

    Just to clarify--are these screwed into the wood, or screwed into t-nuts?

    Done this a coupe of times flush/below the PF surface, its a hack/rough job but it worked out for me, i used a small flat blade screwdriver & pry'd out the wood around the broken screw & i modded up these old Vise grips on the bench grinder & got them out, Filled the core hole with bamboo wood & filled it up the rest with quick wood putty, end result it looked fine & was worth it,

    Drill a hole in it big enough for an EZ out. Left handed bit would be best. If the broken part isn't flat enough try using a punch to put a divot big enough to let the drill bit start.

    Can you post a picture of it?

    Into the wood, below the surface, no nut underneath. It appears as if this happened twice and someone attempted to remove them then just drilled yet a third hole. Stuff now doesn't line up and I want to attempt to fix it.

    Depends where it is? I had one in my machine that I took a very small drill bit and drilled holes around it through the playfield. I made sure to stay within the indention of the post so that when I was done it would be covered. After drilling some of the screw off and giving it some wiggle room I used a small punch insert through the underside of the playfield to knock out the piece. Then used wood filler. You would have no idea it is there unless you removed the new post.

    For the record mine had snapped off below the level of the pf. Game came like that and I had no idea there was a problem until the new post wouldn't screw in.

    mine was from underneath PF, for me Ezy outs/Extractors wouldn't work smallest size is to big,

    I have found Vids recomm to use a Woodcraft screw extractor (available in 3 sizes 1/4, 5/16 & 3/8) to be really effective. The extractor drills around the culprit which allows it to be removed & then dowel the resultant hole. Need to be very careful to go around the broken screw to avoid shattering the extractor.

    Drill from the bottom, punch tap it out, fill in with bondo?

    This looks like a cool tool, but the last part reminded me of this

    #12 4 years ago

    If extractors won't work, I would drill a hole through a slab of hardwood on a drill press to make a template. Then clamp that template to the playfield with the hole centered over the screw. This makes a guide so you can drill the screw out without drifting. You may need to repair the hole by setting a plug into the playfield and drilling a new hole.

    I'd go the same way, using a very small drill bit.

    Punch it down a bit. When you know where it is going to come through the bottom drill a relief hole up. Finish punching it down and through. The top is way more important than the bottom so you don't want widening or splintering. After it is out there are many ways to fill and close up the hole for reuse.

    #15 3 years ago

    I decided to use a small drill bit and slowly and carefully drilled around it from the bottom. When I got far enough to get a small pair if vice grips on it, I unscrewed it that way. I was able to still use the rest of the hole with a replacement post.

    This is what I have and I constantly curse while using it. Screw breaks are terrible.

    I'M LOOKING YOU GOTTLIEB WITH ALL YOUR LOCK-TITE.

    I like those screw extractors that Vid showed the best.

    If you don't have any extractors you can make one from a 1/4" or 3/8" roll/spring pin. Load it into your drill and file an edge on the pin and it will dig out around a broken screw.
