Quoted from DropTarget:What's the best way to remove the threads from a post screw that has snapped off in the playfield? I'm assuming it has to be drilled out.
It snapped flush with the top of the pf.
Use a Tubular Screw Extractor from the backside
Don't drill all the way through, just about 3/4 of the way, then tap shaft out from the face side.
Plug hole with a 1/4" dowel, or just use a T-nut and machine threaded post.
