Quoted from orlandu81:
Just wanted to give a shout out to this key post...extremely helpful. I thought my machine was dialed in 100% but was noticing the ball jiggling around maybe 10-20% of the time on the inner loop shot, so I pulled the ramps AGAIN and really studied the angles. Luckily I didn't have to redrill holes or any of that, but I did bend the guide so that the ball would not get caught up on the stupid diverter screws. I also didn't have to remove the plastic piece under the guide to do this, just bent it until it was enough to miss the screws. Finally my orbit and outer garage shot are smooth (I fixed them previously), and now finally my inner loop shot is also 100% smooth. Thanks iepinball for the reminder about this angle!
The RAM forum continues to enhance my enjoyment of this hobby: I thought that I had my RAM pretty well dialed in but after reading about the upper loop diverter and seeing too many shots lose momentum going around it, decided to remove both ramps, house and spaceship. While I didn't completely reform the left metal guide, the top section was curved too tight and the guide to the subway drop was on a 60-70 degree angle instead of square.
As for the diverter itself, I opted to install a ~4" aluminum plate over the steel diverter plate with a small double sided gel tape adjacent to the two mounting screws. Not as involved or elegant as the modified post I've seen on earlier posts, but it's resulted in bullets shooting around the loop off the upper right flipper. Didn't hurt that this was a perfect opportunity to clean the now accessible lanes.
Coincidentally, I found a partial crack in the spaceship mount while trying to get access to the upper loop. Rather than wait for it to fail I overlayed a small 1/8" thick plexiglass layer secured by the existing 2 screws to reinforce it. A hobbyist's job is never done...
