Quoted from jzdziarski:question: has anyone had issues with occasional ball hangups between the mini/main playfield on the cliffy protectors? do you have to shim the mini playfield where it bolts to the main playfield, or is there a better way to get the mini to come up just a smidge?
Yes. Only way I know of is to shim with washers where the bolts go on top. If there's a better way I'd like to know also.
