Quoted from pinbuoy:to me, I'm oldschool (get off my lawn)
all flippers should be parallel to the inline path of the ball.
i.e. the ball should flow smoothly from the inline plastic to the flipper....
if the ball "bumps" on its transition from the inlane to the flipper, something isn't right.
Typically, its been said that you stick a toothpick in the hole and
back of the flipper (w rubber on) rests against the toothpick
BUT
don't let that "guide" override the judgement of parallel...
That all being said, it's your machine, do your thing
(For example my NIB AC//DC vault pro came w the flippers slightly misaligned)
HTF does that happen?
and for months I was too lazy to change it...
where as my used DP came w the flippers too low.
I changed that quick.
Hope this ramble helps
It happens by designing/testing of the games. They are drooped for a reason, to make certain shots. Yes in the old days a tooth pick and rest it on it to adjust. But newer sterns are at the tip of the flipper and no toothpick is used. But as with jp2, dp and others the bottom flippers are drooped slightly off to make shots.
