Quoted from CrazyLevi:
The ball was getting stuck on rollovers and right above the flipper on the upper playfield.
Seems games with star rollovers are a very bad choice to use these protectors with - though I don't understand why you'd use them at all unless the playfield is a lost cause absolute mess.
The FLippers' Bally Star Trek was also at magfest in the free play bank. I played one game on it. A ball got stuck on a rollover (a regular one) necessitating a tilt. What else is new.
That's because whoever set it up did not set up right or just did not know what the fuck they were doing. I have a Stern Big Game with 5 rollovers and I have no problems. Not one. That 's because I raised the inserts .030" to match the thickness of the polycarbonate.
I have a Stern Seawitch with 2 rollovers that I also made a poly protector for. Again, I raised the inserts. I had a brief hangup problem with one rollover and a bit of work with a file in dressing the edge made it problem free.
Both of these pins play fast. I guarantee you would not bitch about how they play.
I have one more older Stern with a beautiful play field and very nice inserts. It is all original. On some inserts I am starting to get a bit of ball deflection at 3 or 4 inserts; I don't like that. So I am going to make a poly protector for it, as well. This is for two reasons: I want to keep my nicely waxed play field looking nice and I don't like ball deflections.
Shit man, ever since this post got started you come in with a negative attitude about play field protectors. It almost seems like you are coming from the planet of since-it-was-not-my-idea-then-it-is-not-any-good.
You oughta try lightening up a bit ---and look at the other side.
