Quoted from umk298:Thanks, I'll definitely give that a try since the issue still seems to be happening (albeit rarely) after I taped the bottom one.
I unscrewed the right ramp habitrail and re-positioned it to hug the orbit, which fixed the ball bounce issue there. Thanks again to EaglePin for sending me the pictures of his machine for that.
The stuck ball issue with the one-way gate at the bottom of the bumpers still happens after I bent the right side of the gate a bit to make it more flush with the post rubber next to it, but it is a little better and doesn't happen as frequently now. I guess I'll still have to play around with it to see if there's anything else I can do to make it better.
I appreciate all the advice & input that I've gotten from everyone.
Regarding the ball stuck issue at the one-way gate at the entrance to the pop bumper area, I solved that problem with a piece of rubber (can't remember for sure, but it's either 1/8" or 1/4" thick with adhesive on one side). I cut out an appropriate shape and stuck it onto the pf, as shown in the pics - ball hasn't gotten stuck there ever since (several months now). In both pics, look for the rubber (black) on the pf right below the right, lower corner of the one-way gate. And yes, getting the correct shape of the rubber and location on the pf did require a lot of trial & error, but it's working very well now. Also, it can't be seen from the player's position. Originally I tried bending the gate, but was never satisfied with the results.
