I am doing a playfield swap on a HG machine, moving from the hammered original to a new CPR playfield. I've started repopulating the new PF and just noticed that there is cracking around three of the inserts. The cracked clear goers all the way around the circumference of the insert. The pics are tricky, but hopefully they illustrate the issue:
Is there anything I can do to prevent these from getting worse once balls start rolling? I'm not sure what caused this issue. I've been pretty gentle, and any hammering I did was done on a flat, protected tabletop surface before anything else was done. But, of course I was hammering t-nuts and nails into it.
Not sure if there is anything that can be done, short of taking everything off of it and getting it re-cleared? Any advice would be appreciated.
Here's a look at the work in progress!
