Quoted from JohnTTwo:
I really do not know if ths is the right place to post this, but I watched a cool video from Jersey Jacks on flippers last week and can't find the thread.
I have 2 Addams family games and one played so much harder, I realized the flippers were pointing down the drain like 2 degrees compared to the other machine. Moved the flippers up so little you can hardly notice it and it is like a new game!
What is the best way to set the angle of flippers on a game?
My rule of thumb is to make it a perfect continuation of the angle of the return lane (if present), to prevent any ball hop or slow down. This way the ball whips up or down between flipper bat and lane. The old Williams generally still line up well and don't often require much, though sometimes adjusting said return lane is needed to get it as smooth as possible. Using Cliffy replacement lane guides on my old Bally's like 8BD and Flash Gordon makes it smooth as butter and fast as hell, combined with a modern Fliptronics system with 11630's as described in this thread. My single fave mod of all, thanks to vid1900 and this thread!
