Quoted from Marvin:
Before your adjust the switch blade just remove the switch temporally first. If the problem ceases, you know it's the switch, if it continues then you need to look elsewhere. It's just two screws that hold it in place.
As you suggested, I removed the switch (great suggestion, btw). I added a 2-second slo-motion video to the album below. If you download it and step through, you can see what I was describing in an earlier post. The ball is airborne when it leaves the ramp. When it "lands" on the edge of the wireform, the landing location is almost precisely where the switch was previously located. Since the switch isn't there to alter it's progress, the ball slams into the plastic/rubber on the upper PF and knocks it back on the wireform. If the switch were there, it's unclear if it would have fired properly (since a clean activation depends on the ball being on the center of the wireform, which isn't the case). Do you concur and see what I'm seeing?
At this point, I need JJP/Pat to advise my next steps. From my perspective, simply tweaking the switch isn't going to solve this problem.
From my "layman" perspective, I believe there are 2 design issues to protect against strong hits where the ball is airborne during the ramp/wireform transition:
- the wireform should have a guard rail on the inside (leading up to the Betty diverter).
- the wireform entry switch, if necessary, should be further from the ramp/wireform transition (ideally, right before entering the Betty diverter).
Caveat I design software for a living, not pinball machines. Nevertheless, I've owned many machines and have worked/restored on a fair number.
Pat's opinion is obviously all that matters here, but since my machine is unhappy, I can't help but comment on what might solve my problem. I love this game and want to play it without unnatural ball activity...
