Quoted from DNO:
My game has this damage as well, cutting by the protector isn't going to help much as the damage is from the leg, well outside of the protector.
In my case the game was being played and the legs worked a little loose, allowing the leg to dig into the decal.
even after tightening the legs, they still were pretty much right against the decal, that's not really right.
Its almost as if the leg bends around the protector and into the cabinet, making the metal shim protector basically useless.
I put some of the plastic "slightly larger than the leg" type protectors on and called it a day, mine is a route game anyway.
but I would recommend that people keep the leg bolts tight, and inspect the gap between the leg and cabinet. and you may need to add more protection to be safe.
Yeah it is definitely more about the way the top flange of the leg is formed. I've found it varies quite a bit. It's like some legs are "over-formed" or something. The mounting face forming overall less than 90 degrees, meaning the outer edges project toward the cabinet. When pressing, the same dies can give a different result depending on a few factors, one being material, another being tonnage (or force). More force or less springy material will affect the "set" or the amount of "spring back". If the cabinet protector standoffs were slightly larger all would be fine, one solution.
Example, 1 out of 4 of my TNA legs touches the cabinet no matter where I bolt it on. All other legs there is about 1mm gap at minimum, both sides.
It just means I put that leg on the back, so that it rubs on the rear cabinet face. Just a slightly off kilter pressing, slightly out of tolerance in some way.
Larger leg protector standoffs would be the practical fix, I would rekon.
I don't like the artwork cut away around the leg outline. Same with playfields incidentally, and deleted art around posts etc. , because everyone can't achieve as good as we could 30 years ago, apparently.
