Quote from: pinball god on March 21, 2013, 08:08:01 PMIf you have a vernier, measure the diameter of the original hole and that of the new. My fh playfield had been cc'd that much that the holes were way smaller all round. I had to, by memory, redrill all my holes, not only for the pop bumpers. Please check the other holes for say metal posts that go through and tightened with a nut etc. It really annoyed me. I even had to open up the opening where the pop bumper fits with a Dowell and sand paper. That central area of the p/bumper you have pictured, I don't know its correct name. So try out various assemblies prior to doing the reassembly as its easier to drill with nothing on the pf.Hope this is not the case for you. Thankfully no issue with the other holes, just these ones. To remove them from the existing playfield I had to tap them out with a hammer so I expected to have to knock them back into the new playfield the same way but it does make me a little nervous. I gather they must be designed this way with the hole smaller than the screw so that they can't vibrate loose during bumper operation. There just I little tighter than I expected though.
