Quoted from maxpower:I know I said I was done here, but since I solved my problem only with the help and advice of people here, I felt obligated to come back and describe in more detail what the problem was and how I fixed it. Also, I suspect that others may have the same problem and not even realize it, as I did not until recently, and this might help them.
The problem was this: When the ball comes down from the right orbit with high velocity, i.e., from the right orbit gate, the ball should feed the right flipper. When the ball comes down from the right orbit with low velocity, such as when the ball falls onto the PF from a short or soft plunge, the ball should hit the top of the right sling and bounce. This is by design. To quote damadczar , "On a slow rolling ball or a soft plunge, it should hit the top of the slings. That's why the ever popular right side nudge on a soft plunge became en vogue. If the ball is traveling fast around the loop it should go to the right flipper." TheNoTrashCougar replied, saying, "This is 100% correct for the record." Bowen Kerins explains it very well here, at 10:45: (this whole video is amazing, btw. I am now a Bowen Kerins fan)
My machine was not doing this. Very not doing this. On a slow ball from the right orbit, the ball on my machine would hit the rubber ring just south of the right metal orbit guide, bounce off of it, and not even come close to hitting the top of the right sling, as I showed in a previously posted video.
After "pulling the plastic" (look at me, learning pinball terminology), I could better see the real issue:

As you can see, the edge of the orbit guide was impinging on the rubber ring and the ball. Additionally, the guide was twisted, as you can sort of see here:

First, I put pressure on the guide to bend it and take the twist out of it. I could see that this was not enough to solve the problem, so I thought the post holding the end of the guide (where it is riveted) might have enough slop in the through-hole to move the post in a bit. I found the nut underneath and was able to move it slightly:

This was still not enough to move the guide completely out of the way of the rubber, so I pulled out (toward the PF right edge) on the rubber ring post closest to the guide edge, moving the rubber out slightly. I also worked the rubber around to get the chewed-up part out of the way:

All three of these actions helped, and it was better:
Minor adjustments were necessary to cause the ball to completely behave as it should, and I had to bend the guide back in a bit to get it "dialed in," as the young folk around here are fond of saying. (I understand there is a pinball machine by this name. Coincidence?? )
Big shout-outs to sataneatscheese, Oscilated, namyzzo, falcon950, TheNoTrashCougar, and everyone else who PMed me with great advice and encouragement. Honestly, I was just worried about screwing up my playfield -- breaking something off, wood splinters everywhere -- the imagination ran wild. And the fact that I had to bend, pry, and twist things on my brand new 9-grand toy put a bit of a knot in my stomach. But here we are.
And since I discovered today that my TNA is at only a 6 degree pitch, not 6.5 as it should be, now I just need my daughter's boyfriend, Buellxb12r, to come over here and get it even MORE dialed-in.
