Some info, and a question.
We installed the extra outlane post in 2nd (highest) position, and put the smallest (3/8" OD) o-ring on it. A 3/8" OD ring on the post between inner lanes caused the ball to usually get stuck when going through leftmost inner lane, as documented in the thread. I don't like cutting down an o-ring, cause I'm sloppy at it, it looks bad (IMO), and they always seem to rotate to the thickest diameter after awhile.
If you want something on that post, for now, I found that 5/32" (4 mm) heat shrink tubing works well over the post, but only lasts ~50-100 games (depends on game length). I'll try to search some thin rubber sleeves with ~4 mm ID that will last longer.
We never had the ball fall out of our trough on our LE, but the ball did get stuck in the upper part of the trough often enough to be annoying. We'd have to wait for a ball search to make a bump that would kick it out and have it go into the trough and be registered, Kind of a bummer on a ball save. So we put two 3/8" rubber pads/bumpers at the end of the trough, under the playfield (see photo, from underneath). Seems to have solved the problem so far, and you cannot see them from above.
Had an unusual ball stick - at the top of the plunger lane, trying for a soft plunge. I couldn't nudge the ball out (tilt warnings). So I waited the 4 (or so) ball search cycles until I got an extra ball. It dropped the ball from the Wonkavator, and while I had 2 balls for awhile (once the active one nudged the stuck ball out), I also lost a locked ball in the Wonkavator.
We've had our game at both 7.5 and ~6.8-7.0 degrees. At both settings, we get stuck balls in the lane above the pop bumpers. It happens a lot when the bumpers kick the ball back up. It kills the momentum in a game, cause nudging won't get it out & we have to wait for ball search, sometimes 2 cycles. Anyone else have this problem? Is there an adjustment to solve it? Since it's under a bunch of stuff, I'm reluctant to take the time to take it apart unless I know I have to.
