I have a NOS EM playfield that I was going to get re-cleared and then install in my machine. It's a mid-70's game, but I have no idea how old this playfield is. Upon closer inspection the other day, I noticed it 'sags' in both directions. Side to side is the worst, while top to bottom is very minimal. I put a straight edge across it and checked the gap with feeler gauges.
It was ~5/64" at the bottom, then increased to ~3/32" a little more than 1/3 of the way up, then decreased from there until the top at ~3/64".
First, is this too much sag to be properly clear coated?
Second, is this something to even be concerned about?
In the pic, you're looking at the bottom edge as it's laying face down. I had to put the white line in the pic because the reflection of the gap on the floor makes it look much bigger than it is.
Thanks for any feedback.
