OP

Quoted from goingincirclez:

Thanks for the comments all. The target decals are first-shot first-print efforts I applied while the targets were installed in the game. I need to increase the size slightly to better fill the face, and prevent snags as they drop - Incredibly, the thickness of the paper sometimes snags the metal frame, because the decals aren't long enough to extend past the frame while raised. I've accommodated that exact concern on WMS and GTB targets I designed... but here I re-used a template I made for Stern targets which apparently fit just a bit differently and didn't have this issue (so much for Sterns and Ballys being the "same"). So yes, a revision is planned, and I'll pull the mechs to square up the application this time. OCD placated!
They are very durable. I use printable adhesive vinyl, and always overlay with mylar before cutting them out. The glossy finish is slick and easy to clean too. Durability is well proven as I made custom "S O X" targets for a Big Hurt that went on location 4 years ago, and they STILL look great despite the rest of the game wearing heavily (it's popular!) over the years.
I could almost not worry about the BG crack, but every time I remove the BG it flexes and shifts at that faultline seam despite my mylar reinforcement. So it's a matter of when, not "if", it will finally separate toward disaster. The mostly-absent (corroded) lift bar certainly isn't helping this scenario. But I have a vision: if I try to replace the bar (I did buy a new one) to make the glass more stable & easier/safer to handle, the process of doing so will make the glass shatter, etc (those bars aren't easy to remove or replace even on *good* glass!)... so I fear I'm ultimately damned whatever I do, or don't :/
