Sorry for the delay but a Massive thanks you to pop bumper Pete for taking the time to try help flatten my playfield we pushed our luck as far as we were willing but with no luck just wouldn't soften but Pete convinced me it wouldn't be that hard to cut out another one and he was spot on.
$40 for new plexiglass and an hour on a scroll saw and I have a new one.
Thanks also to everyone for there suggestions and help
