Quoted from bakerhillpins:
The concerns here are many. I'm assuming there's some screw above the PF surface. But even with that you're in for a fight. The screw is small so there's not much actual screw to work with and it's in there tight enough to break the shaft as well. You'll probably get one chance at an alternate extraction method before you're hosed and have to "dig" it out. If you can't grab it with needle nose pliers as Kevlar51 suggests (or a small pair of vice grips) you may be able to cut/grind it to help the process by providing a better surface to grab it with. But both of these options remove some of the screw so that's going to make it more fragile.
I've had success by cutting/grinding the shaft in the following 2 ways in the past. But with such a small screw diameter there's not much room to work with:
grind two flat spots on either side of screw (flat spots would be parallel to each other) with a Dremmel tool and then use the pliers/vice grips to grip on the flats and carefully back it out.
cut/grind a small grove into the shaft of the screw with a Dremmel tool and then use a flat blade screwdriver to carefully back it out.
If you score the PF with the Dremmel it's not a huge issue as it's under the bumper. But I do understand the pain that would cause.
I'm interested to hear of other ideas as I'm probably missing some easier method.
Yeah, I agree with everything you are saying. It was a predrilled hole and I barely torqued and it broke flat with the playfield lol.. I am going to look at all of the dremel bits in the known universe and see what will work best. I am thinking of trying to grind it out
Of existence. It's such a bs thing to try and deal with!
