Quoted from snaroff:
I've owned 3 Trons...all with 4 posts that get hammered. Thousands of play...no damage. Hitting a post shouldn't cause PF damage...! My LOTR has over 10k plays with posts that get hammered and 0 damage.
Based on the little I know, I would bet the post isn't secured well. As the post loosens and gets hammered, it chips away @ the PF. One of the posts on my KISS would loosen after 50 plays or so. Added a lock washer and hasn't loosened since.
I think my previous post was misunderstood. (Maybe my post wasn't secured well )
Sure-I agree in theory the playfield *should not* get damaged.
By your own admission you had a post on a game loosen in 50 plays. Also you agree as a loose post gets hammered it chips at the playfield.
You are very meticulous with your games, so you would pay attention more. Further you stated you had to add a lock washer that wasn't there. Imagine if that loose post were on a route game with nobody paying attention like you do.
So to me, it seems very plausible that at a location with a staff not as diligent and caring as you and the other collectors here could have a post loosen and cause the damage I observed.
Again, I'm not saying anyone should accept the playfield issues, I am just simply saying that I am not surprised that in *that* particular post location that I saw damage.
I'll stop there-nothing more that I can add without repeating myself.
