I have a donor playfield for my JP which is missing the "S" insert (everything else is really nice condition, even came with the rails on it). On my original playfield I'd like to remove the S insert and swap it over. I assume they are expoxied/glued in and it might be a tough thing to remove without breaking. Any hints or tips? My one thought is to cut with an xacto blade around it and see if I can nudge it out. If not then maybe cutting the wood around it as I am not needing to save the old playfield.
